Looks to be a series 3 Eaton 12 bolt truck carrier.

Re: what kind of posi is this?

It does look like a factory Eaton posi. It hasn't exactly been stored well, though. 3 series is not a very good term for carrier break on a truck 12 bolt as it overlaps the middle of the 3 range.

3.73 and up would be the 4 series carrier if you want and 3.42 and down would be 3. Need to know what gear it was originally on it to know if it matches up with yours. $95 not a bad deal IMO.
