Rear end Identification
 

i have recently purchased my first nine inch and am trying to absorb as much information as possible.. i've been trying my best to ID what i have before going too far, but i find the information told to me misleading.

casting numbers:

on case: WAR
A-8 (or A-B)
4825

on housing plate:

WBS AE1 00
3 50 B12 0 (made in Canada)

i am just learning so bear with me.. if there are any numbers i have missed or ways to ID 'er i'd appreciate the help!

oh and the guy i got it off of thought it to be out of a '63 something or other.. i dont know if this hold value or not.
