Still looking. I'd even take a complete booster if someone has a good one.

Thanks for the info Rob. looks like I'll have a plan B now😉

I researched Jack's parts kits (at his request) and confirm the NSN is applicable to the 2-1/2 ton truck. I suspect they would be a pretty rare kit these days.

Yes, I was down to his place today to take a look. Unfortunately, it's not for this truck. We sat with the parts book and some of the kit will work, but not all. Thinking it's M35 or even a 5 ton

There was some commonality between the various airpacs, however I can offer some insight into this part number. Note that I have not seen the kit itself.....only the part numbers.

First, the part number of 35907-389250. The first part is a codification for the manufacturer. In this case however, 35907 is Canadian Army.

Jack sent me some further info including the full NSN, the supplier and the dates on the package.

The NSN of 2530-21-861-5692 tells us that it is a Canadian part number from around early 70s codification. The 21 is Cdn, and the remaining 7 digits are sequential. As benchmarks, a 1970 Jeep is a number of 856-9142 while parts for a 1976 chevrolet 5/4 ton commonly fall into the 21-870-xxxx parts range.

I tried to query the numbers at work, and they went nowhere, and I thought that would be the end of it. I also looked in my Canadian Deuce parts manual dated mid 70s, and it only gave a US NSN for the kit, along with a penned in later US numbered kit. But when I got home tonight, I remembered my old 1984 microfiche so I looked up the part number on there. It gives direct reference to the part kit being for the 2-1/2 ton.

The M35 did not exist in Canadian inventory at that time, so we would not have had kits made up for that purpose. And if the kit was for the 5 ton, then the microfiche would have reflected that.

The mystery deepens slightly when we find that the actual kits in question were supplied by Milquip (formerly automobiles rene gagnon if I recall correctly) in August of 1984. By that time, the deuce was very close to heading out the door. Some did remain in service as late as 1987 though, and back then (early computer days) it was not uncommon for the supply system to re-supply even if the vehicle type had left the service.

So there are the ramblings of a madman....take it for what it's worth. My money still says it is a kit for the M135.

Wow! Thanks for all the effort Rob, it's much appreciated! I'll be taking a closer look at the kit and booster later this week and let you know how things work out.
