The 78 number is the case used from '37 to '39. The gears inside may be '37-'38, or the more popular '39-'48.

The 78 case was also used in commercials (light pickups) up till somewhere in early 1951. It's the one most folks use to build a what is known as a "39" transmission. The double detent shift tower from 1938 on is preferred. The gears from side shifters can be used in the top shifter to make up a torque tube drive application. Pickups had open drive after 1942 so the output shaft is different but the rest of it may have some value if the ratio is usable.

I have no idea on the other numbers.

Ok, so I have 2 early and one 81A-7222. I couldn't find a casting number on outside of the early ones.

What are they worth, in good condition?

The early ones? Find someone that needs one and tell him "Any reasonable offer."

That one, if it has the 91A forks, should be worthy of taking it to a swap meet. I'd probably clean it up nice and put a proper label on it saying what it is, and maybe ask $75 and take $50. Maybe a little more if it's complete with shifter and knob.

The reproduction 91A shift forks are expensive but I think Mac VP is out of them. Who knows if they will be reproduced again. Originals is good shape are still worth a good bit since folks are always looking for the to upgrade the older transmissions. Mac is asking $175 so keep that in mind. Mac has a lot of info on his site to ID these old units.

That's not to say they are the 91A forks. Look on the underside for the large 91A cast in numbers.
