My 47 Loadmaster 2 Ton has a leak in the PTO. The place I'm working with to try to get some seals are asking for the transmission model. After scraping 70 years of gunk off, I've found several numbers, but having trouble getting many online hits. Right by the shifter, on top of trans I have a " F 137". Also on the top of the transmission but on the driver side of the shifter I have a "590511" and a bowtie 10. On the side of the transmission also on the driver side, there are some characters but they are really hard to make out. Even after cleaning with solvent and a wire brush I'm still not sure. Something like "F1A70" with a big 3 below it. I'm pretty confident in the F, 1 and the 0. The A and 7 could be a 4 and who knows. The large 3 below those numbers is easy to make out. I know this is a long shot. Any ideas?
Oh yeah, the PTO is a Muncie with P64 stamped on a tag. I would think that would be enough for them, but they want the transmission model as well.
