SD,
Check your casting number again, your one number short. I believe you have 590474 (p/n 590524) which is a Second Half of 1931 thru 47 truck 4-speed transmission.
The date code (F177) could be June 17 of 1937 or 1947, but with the Bow Tie I'm betting it's '37 (I don't think they put the Bow Tie on castings in the late 40's, but I could be wrong).
Someone else will be along to advise you on the swap.
