Looks like a 8/80-4/85 four speed. After that they had a dummy spacer and longer tailshaft to match the length of the H55F. Depending on what market it's from could be either a H41 or H42.
@Jbomb76 that looks like an early FJ60 H42 transmission with a split case. Should have a 19 spline output. Works 81-3/85 or so.
They are good transmissions, but usually available for about $100 or free. I have at least one in the parts pile. I don't want to rain on your parade, but used H42's are not worth much, even though they are good.
The split case is the valuable part.
Also, you should list precise miles if you want a premium price.. If you don't know, state that, but then it's worth average $$.
