590474 I think Chevy, because it has a Chevy bow tie above the numbers. The other numbers I see are on the shift plate and they are (590511) I don’t know if that helps? I don’t know how to include a picture or I would.
I'm going out on a limb here and saying that transmission is from the early 30's.
My question now is what’s a better transmission to go with 3 or 4 speed? It’s going on a 1955 235. I won’t be doing any towing, or burning rubber.
High (3rd) gear will be the same in both transmissions at 1:1, but the 41-47 truck trans will have 2nd and 3rd gears synchronized...the early trans may not be synchronized.
