Need help identifying lower end (pics)

[Britcheflee]

Can anyone identify this lower end unit I picked up from a garage sale - it looks like it has never been used - the water pump cover has the following numbers on it:
464060 the only other id on it is BP on the prop. I got it for $10 and I am hoping to sell it to help pay for the motor work on my old mercury.

It's Chrysler, c. 1960s-70s, and a larger one at that. Likely a 105 or 130.

It is hard to tell if it has been completely cleaned and sand blasted and re-painted or if it is an original old part which has never been used - have not cracked the oil drain screw yet to see if there is any lube in there. I hear a squeaking when i turn the drive shaft but i think that is the rubber impeller rubbing on the internal housing. Is there a market for this?
