What Does This Overdrive Tranny Fit?

[wayneyada]

Hello All -

I haven't posted in quite awhile, but I do need some assistance. I have an overdrive tranny with the case stamped 8M-7222. I found that model number online in one chat-room and it was associated with a 1952 F1 pickup. Can anyone confirm/deny if that's what it came out of. What else might it have come out of? Here's a photo:

Thanks in advance!
