  1. Thank you. I'll see if I can get in touch with Mike Gully.
  2. I have had the Freightliner Powerliner cabover on my list of to do model projects for years but just can't find the information I need. I was wondering if anyone has one or has access to one which they could photograph for me. They seem to be something of a rare beast and I'm pretty sure I won't find one in the UK. I'm particularly interested in front end frame detail such as spring hangars, cab mounts and how the radiator is mounted. It's all a bit complicated in there and I can't figure it out so any help would be appreciated. I would really need someone to get in there with a camera and take a whole load of shots. Alastair
  3. All the early flat backed cab R's I have seen had what looks like a one piece hood without the fender seam. I think Mack may have started getting the hoods from a different supplier sometime in the 70's and their manufacture process involved bonding on the fenders so for this reason the seam became a feature. Perhaps because it was quite distinctive it was kept for a while when they switched back to single piece hoods. It would be interesting to know if Mack used more than one supplier at the same time and had both variants available. Later R model hoods didn't have the seam or that slight step in further down the fender either. I suppose Mack just decided to clean up the design a bit.
  4. This topic came up a few years back but I can't find the thread. I seem to remember someone saying that the hoods were not necessarily made by the same manufacturer so the differences were down to the particular process employed by each manufacturer.
  5. I still think there is no difference and that all the plus 3 back panels were the same excepting the addition of the vertical body crease some time in the late 70's. The top corners of the roof panel were substantially radiused so the bulge appears more prominent when the cab is viewed from the front corner but less when the cab is viewed side on. Follow this link to see this. https://www.purplewave.com/auction/120228/item/A6751 I'd also argue that, after the plus 3 cab was introduced, the long grab handle was standard on all the R,U,DM cabs including the flat back cab which was retained as standard on the U. It looks like the panel was modified to eliminate the mounting bump for the old short handle. The U could be ordered with a plus 3 cab. There was one for sale on here a few years ago.
  6. I think the U model came with the flat backed cab as standard to preserve the 90 inch BBC but could be specd. with a plus 3 cab if BBC wasn't critical. I think the body line crease behind the grab handle appeared in the late 70's but wasn't present on the earlier plus 3 cabs. Apart from that I can't see any difference in the curvature of the plus 3 back panel.
  7. https://chuckhenry.com/inventory/tow+trucks/1973-mack-rs700l-solomon-ks-5be0c93db4763d2c5a513a62/ Came across this. Big price tag but I hope it goes to a good home.
  8. Depends on how much scratch building you want to do. Vlad is spot on as usual. The US spec MH had an entirely new frame which was also used on the Super-liner 2. Here's a link to a series of articles on upgrading the old Italeri Superliner including scratch building the correct frame. I'd have thought you could pretty much follow this but using the MH Cab. https://public.fotki.com/modeltrucks25thscale/model_magazine_articles/scale_auto_enthousiast/sae_2000-2004/sae_2001_02__februari/saefeb01p1.html
  9. That does add to the confusion! But there may still be an explanation...... I think your last line was meant to be 'The 1985 was built in Allentown'. This would make sense because I believe Hayward closed in the early 1980's and all production of Hayward models was transferred east. The hood ridge appeared roughly about the time the RS600L got the Value-liner moniker but can also be found on some very late model RS700's. I have also seen it on a few metal dash RS700's so I imagine that replacement hoods from about 1978 also had this ridge. I think the ridge may had served as a strengthening rib but I'm not sure. As regards the fact that the hoods and BBC seem to be the same on both your trucks despite the spec sheet dimensions saying otherwise, this is my best guess: On RS700's, pre Value-Liner RS600's and first Generation Super-Liners the back edge of the hood comes right up to the outer edge of the cowl and you often see paint/hood chips on older trucks. On later 1980's models there is often a gap between the back end of the hood and the outer edge of the cowl. I would say this gap is about an inch but I don't know if it is as much as 1.75. I always imagined this gap was to stop the hood and cowl bashing together on trucks with air ride cabs but maybe it killed two birds with one stone by moving the hood forward a bit to make space for the rad mounted intercooler. Just a guess though. You could try measuring from the bumper to the back of the cab as I think hoods tend to move around a bit as well.
  10. I think these are the dimensions you want: 1977 RS700L BBC= 117 inches Bumper to front wheel centre= 28 inches 1977 RS600L BBC = 105 inches Bumper to front wheel centre= 28 inches 1985 RS600L Value-Liner BBC = 106.75 inches Bumper to front wheel centre= 29.75 inches The difference in 1970's models was a clear 12 inches but the introduction of the intercooler ahead of the radiator added an extra 1.75 inches to the front end of the RS 600L so the difference between your RS600L and an RS700L should be 10.25 inches. I've no experience of real tucks so can only speak theoretically. I have made reasonably accurate scale models of both the RS700L and RS600L. The front cab mounts for a 77 RS 700L and Value-liner look the same and also had one of the battery box mounts incorporated. On the RS700L the cab/battery box bracket was the rear support for the battery box but on the Value-liner it was swapped to become the front support. I don't know if the battery box/ cab support mounting holes for the front and back were in the same position on the frame and therefore interchangeable on both the 600 and 700 models but it might be worth looking into. Then there would still be the extra 1.75 inches at the front to consider as well as the other things Vlad listed. spec sheet0001.pdf
  11. Just stumbled across this. Might be helpful as it looks pretty much identical to the AMT R685ST. https://www.purplewave.com/auction/151118A/item/L5144
  12. Hello Steven, Always good to see a fellow model maker here. I'm assuming you have the AMT R685ST kit which, as Vladislav says, is 1:25. It's a pretty good kit which dates back to the 1970's so I think it fairly accurately represents an R685 from about 1976 or 77. The front end is a taperleaf spring set up and is well detailed on the kit so I wouldn't have thought you'd have any problems with it. The rear is a tandem Camelback spring set up. There's no airbag. Again, it's pretty well represented on the kit. If you want more detail then googling is a good bet but it's also worth visiting truck sales sites such as truckpaper or even ebay as sellers often post close up shots of less accessible areas. Naturally the guys on this site are incredibly knowledgeable and have helped me a lot with my models. I also have a few brochures so I'll have a look through them and see if I can find anything. I know there is a good image of a camelback somewhere. As for kits, the ones mentioned in other posts are all available if you look. AMT did the Cruiseliner as well as the R685 in 1:25 and a Superliner in 1:32 as both a tractor or a wrecker. ERTL did the DM600 and DM800 which date back to MPC kits from the early 1970's and all of these kits apart from the 1:32 ones seem to get reissued regularly so you can get them from online model shops and ebay for a reasonable price. Some of the original releases are also sold by private sellers on ebay but the prices can be silly. In 1:24, Italeri did a Superliner which was never branded as a Mack. This kit has been reissued by Italeri, Revell and Heller over the years but the frame/chassis is from Italeri's Freightliner kit and bears little resemblance to a Superliner frame and the cab is not a great copy either. There's not much Mack in his kit so you need to do a lot of work to get it up to standard but you can see that Pawel did a pretty good job if you follow the link in J Hancock's post. I hope this helps. I'll have a rummage through my literature and see if I can't find some images for you. Alastair
  13. I saw that recently. It is a superliner. Also check out the German TV movie 'Fleisch' released in English as 'Spare Parts'. One of the main characters drives a great looking RS700L.
  14. Does this mean that if a non Mack transmission was used then the motor would mount by the bell housing? Looking forward to the pics. Thank you. Alastair
  15. It took me a while to get my bearings looking at those images. Is that an 866 motor and is it the original? Also I thought that Mack engines hung by the transmission case but it looks like you are hanging that by the bell housing. Here's my 1:24 RS700L frame in progress. It shows the front end set up for the smaller radiator. I'd like to do a model of an RL771L which would have the taller radiator so this was the area I was hoping to get a look at to see how it differs.
  16. Just wondering if you could get a picture of the radiator mounts, both on the frame and the radiator, and the front spring hangars on this truck. The high HP motors had a different set up than the Mack straight sixes and I've never managed to get a close look at how it all goes together. I can see that the radiator was deeper and the front cross member isn't there but I thought this and the spring hangers were a one piece casting. Also where does the lower radiator hose attach? All for a future model project.
  17. Thank you. A few years on and off but, short of too many, I've no idea in hours
  18. Finally finished my 1:24 scale Rubber Duck RS700L. It's loosely based on one of the early 70's second unit trucks: metal dash cab, Cummins power and cosmetic damage. With 1:25 scale brother for comparison.
  19. Started out as AMT and ERTL with lots of modifications. Back in the 70's and 80's AMT covered all the major US truck brands and some of the lesser ones as well. ERTL did a couple of Macks and a few Internationals.
  20. Thankyou 1958 F.W.D. Here are some links to my previous model posts. Lmackattack, all's well with me thanks. I'll post some more pictures of the one above soon when I've got it finished. All the best.
  21. Thanks for the pictures and the link. I think I have it covered now. I guess the oil filter is the white one on the right side.
  22. By far the best book on Mack that I have come across. There are already two editions, one with a stars and stripes jacket from the early 70's and a later edition with a superliner on the Jacket which includes the later 70's output. An update would be welcome. It's been nearly 40 years since the last one.
  23. I'm making a scale model of a Cummins powered RS700. I've noticed that a lot of Cummins powered R models have a lubefiner mounted to the pass side cowl but some don't. I don't want to have a lubefiner on the cowl but I don't know what the oil filter would look like or where it goes on a Cummins. Please forgive my mechanical ignorance! I just tend to copy photos online for this kind of thing but I don't always know what I'm copying or what it does. Pictures of model attached. The Cummins is meant to be a 270. Any help appreciated.
  24. Convoy! The one without the skirt looks pretty much like the Rubber Duck Trailmobiles.
