Stop in for a cup of coffee

Who does? Where?
I've only seen a picture of one - no information on who made it or when.
I'm talking early LA, 273/318/340 through 1969.
not sure of the brand, but I just put one from a stack of small block LA water pumps onto my 64 318 poly, bolted in no problem, it sure looks why different but the bolt pattern is the same.
