identify this oil pump..?

Hi guys,

Can anyone identify this oil pump. The guy selling it states that it is a M37 oil pump, and it certainly looks like one - except for the additional outlet (?) on the cover plate.

Has anyone out there seen anything like this and know what the additional port is for?

Thanks,
Louis

I have never seen any reference to a M-37 ever having this type of pump
Looks more like a pressure relief valve on top then a port
It might/maybe be for a civilian 230ci but its not gonna be for the Military 230. The mil 230 oil pump is unique as it has a offset slot in the end of the shaft where the ( Mil ) distributor fits into ( civic oil pumps the slot is centered ) and if I'm correct and that is a PR valve on top than I have my doubts that its for any 230 chrysler engine since the mil ( and civie ) 230's have a pressure relief valve built right into the block.
