Yes it is 1091 in both. This one actually came with some extra parts as well. great to find.

I will work on driving the other one back to the shop for a side by side photo shoot. My son has been recording the whole process and plans on doing a video of bring it home, I will add a link when he finishes it up for those who want to check it out.

engine turns over but the starter is not engaging, so I get to start there with this one. Found a bunch of new / rebuilt / spare parts for this under the seat, great treasure hunt lol. Also discovered that the Mack Dogs for the sides of the hood are much larger that the standard B model Mack dogs? I found a new old stock set of hood "Dogs" for a model B, but they are way to small to fit the hood. Does anyone know where I can find the correct emblems? Are they specific to the B-21 or did they come on other trucks as well? I would guess that they are about 2" bigger then the ones I received.

Pressure washed and clean up.

more pics

Ok, well truck no. 010 is finally home.

I have try'ed them but they are not on line?

Any Ideas on which transmission and rear axle this came with or how to identify? Yes, I will post some pics as well.

Nice looking Barn find, enjoy.

So now old number 009 is running very well, engine and cooling system all sorted out front radiator louvers working correctly, and man does this engine have the torque to spare, no need to exceed 1000 RPM at any time. Drives very nicely I have to admit although Armstrong steering is not my favorite. Anyone do a power steering swap on one? Trans shifts nice with 5th gear overdrive, so far so good, it is actually very fun to drive, and a lot of truck. ha ha. Still have some electrical bugs (corroded connections) to clean up, Alternator is still not working so that is on the list do rebuild as well. All I can say is wow, what a lot of fun. little unsure of the pump at this point and with this cold weather here in Washington I don't want any freezing damage so I will wait until spring to play with that setup. Checked out the brakes on number 010 today and had good pressure and they released, but it is in a little hole from sitting and I was not able to pull it out with my two wheel drive truck, I will be working on it again tomorrow. Engine starter spun but was not engaging into the ring gear so engine is still unknown, but I will post pictures and video soon.

good plan, as one will be enough. enough parts between them to make one nice truck. Question: How do you burn though 5 gallons of gas in an hour? Warm up a Hall Scott. Ha ha.

any idea what it sold for?

This is B-21F10009, originally sold to Seattle Fire Department and sold in 1992 to the guy i bought it from. He bought both of them and took them home, now they both moved to my place. This one (009) was fully restored in 1980-1981 according to records from the Fire department and has some upgraded feature like the air brake lock, tail lights, and some other minor things. So far the brakes are holding pressure, an releasing, it moved a couple inches, rocking it with my truck, should be able to move it this weekend.

Yeah, i couldn't leave it behind. I am now the proud owner of two Mack B-21 Fire Apparatus pump trucks, both 09, and 10 same build up. I haven't brought the second one home yet, that will probably be this weekend.

it is certainly something to be appreciated in person. you can feel the beat of each cylinder, it is amazing.

Rebuilt the fuel pump, and had to remove the oil cooler, it needs rebuilt or replaced. Cleaned the oil pan out, flushed the cooling system, back up and running. Runs super nice and man is it smooth running. drove it around the house today and received a full Armstrong steering workout. This is one amazing rig, torque at 600rpm is incredible, (I only needed the throttle for the sound ha ha), brakes are working good, pump is up next. I ended up buying the twin sister truck as well, so now I have to go bring it home. It appears to be in even better condition than this one.

Washington, south of Seattle in the Auburn area.

Start up and running video 20221206_103420.mp4

She is alive, fired it up tonight! Runs smooth, good oil pressure, air pumped up solid, drives forward and back, stops. Super excited. Man this thing sucks the fuel, and the fuel pump needs to be rebuilt, but so far so good. Going to go through electrical next and make sure everything is working. I will try and get a video of it and share. Mark

Says Mack fire apparatus Sidney Ohio.

Not sure but I recall seeing something, I'll check and let you know where it was built. It was delivered to Seattle and lived there until 1987, we went to the fire department today and received a bunch of data on the truck.

Pressure washed and then it started to snow

Picture of getting it home before cleaning.

Yes the cowl and the nose have extensions, from the cab spec sheet. Mine is a combo of the two but not actually shown. I will check it the Mack historical site. I am super excited to have found this. So far sheet metal is in great shape minimal rust anywhere, but cleaning up may show more. Lots of cleaning to do but so far very solid rig. No visible damage, did the initial pressure wash today. Engine turns free but haven't gone much further. I'll keep posting on progress. Thanks, Mark

I just bought a 1958 Mack B-21 semi cab long nose with the 1091 Hall Scott and 1507 gpm pump serial number 10. It was delivered to Seattle fire department on 12/01/1957. Very cool truck
