Ford rear end help 50's?

This rear was in a 1932 Ford I just bought and I think its a early to mid 50's Ford but not sure. Its a 10 bolt with a four bolt flat pinion flange for the drive shaft and has 4.5 inch bolt circle, the spring perch has a large hole and the flange overlaps the axle tube on each side a good 3/4 of and inch. I can take measurements if needed, any ideas?

 

I got one exactly like that Iknow its from a 54 ford

 

Very light duty ,not worth using really.

 

Was not planning on using it, just want to know what it is to see if I can find a new home for it. Thanks for your help.
