  1. 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.
  2. 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.
  3. 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.
  4. 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
  5. 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.
  6. 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
  7. 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
  8. 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
  9. 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.
  10. Thank you. A few years on and off but, short of too many, I've no idea in hours
  11. 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.
  12. 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.
  13. 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.
  14. 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.
  15. 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.
  16. 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.
  17. Convoy! The one without the skirt looks pretty much like the Rubber Duck Trailmobiles.
  18. Only one other picture of that one. I've had the pics for a few years now. I think it was for sale somewhere or other back then. No idea where it is now.
  19. Maybe that's why they switched to the later 1 piece grill and straight bumper. That two piece grill would only fit the bumper with a cut out. I've seen a few with only the top part of the grill but that's because the lower bit has gone missing. That's the first one I've seen that looks like it came out of the factory that way.
  20. Nice looking truck. That is the early Western grill used on both FL/FS and RL/RS models in the late 60's. It was a two part mesh grill with a lower bit that looks like it attached to the bumper and probably hinged when the hood opened. There was also a standard Western bumper which had a cut out for the lower grill panel. This truck is fitted with the heavy duty Mack bumper so I guess they decided to omit the lower grill panel for this reason. The flat panel around the radiator was laid in behind the mesh and if it was dark painted it wouldn't show up but if it was polished ally then it was clearly visible behind the mesh. Both early bumper and grill were replaced in the early 70's with the more familiar single piece western grill with the flat collar around the radiator and a channel bumper with no cut out.
  21. Came across this on Gumtree: https://www.gumtree.com.au/s-ad/wedgefield/trucks/1985-mack-r600/1103285549 Looks like a jacked up R600. Is this a home conversion or would it have been factory?
  22. http://www.ebay.com/itm/1973-Mack-RS700L-Rollback-Truck-Riggers-Special-/142249011816?forcerrptr=true&hash=item211eb3aa68:g:fRcAAOSwUKxYfkKg&item=142249011816 Looks like it needs saving!
  23. Is this it? https://www.google.co.uk/search?q=Mexican+mack&safe=active&bih=855&biw=1280&source=lnms&tbm=isch&sa=X&ved=0ahUKEwillfjO8JPPAhXMKsAKHX1BCeIQ_AUIBigB#imgrc=CEHOE08f7S1lYM%3A It's my understanding that these were basically R Models with a Superliner hood that were assembled in Mexico, possibly by Transomex? You can see it's got R model style tanks with the integral step as well. A bit like the Australian Superliner.
  24. Here's one. I guess it did make it into production. Mack Trucks Australia generally did things their own way. Perhaps the US experience with the shortcomings of the early Cruise-Liners and Super-Liner led them to adopt the tried and tested R model frame for their Cruise Liner, Superliner 1 and 2 and later, the MH Ultraliner. The Australian Value-Liner was also a completely different beast from the US one, again being based on the R model frame. Perhaps the set back axle MH is a kind of COE equivalent of the Aussie Value-Liner which also had a set back front axle.
