Technical Model B transmission identification help needed

I'm trying to figure out what I have here. It was sold as a '32 truck transmission. I'm assuming that's incorrect. I can't find any numbers besides the 3.

 

Looks like a '32 Model B trans to me. Serial # would be on the upper flywheel housing, not the case.

 

I agree with Will. It looks like a Model B transmission used in passenger cars and light commercials (pickup trucks). It is definitely not the "big" (Model BB) truck transmission (which is probably good). The '33-'34 4 cylinder transmission is the same except for the rear mount is different and the shifting tower will not have the place to attach the emergency brake.

Thanks. The brake handle forged into the cover is what threw me off.

 

That is the first one of those I have seen (in pictures, or otherwise). Probably they are not very common. If you don't use it in a build, I would be interested.

 

I plan to use it. I'll have to clean the shifter housing and see if I can get a number.

 

If you will find any number it will probably be a casting number that won't tell you much. The two threaded bosses on the side of the shifter housing were '32 only. If you change to later gears you may need to change the housing. Gears will fit all the way to '39 with the '39 and up being the best. The expert on transmissions is Mac VanPelt and he posts on HAMB.
