A man sent me a picture today of a Hart Parr Plowshare Radiator Cap that was solid cast, not of brass, but what looks like steel (Iron). Cap and plowshare is one piece. I have only seen the brass or pot metal plowshares soldiered to pressed steel caps.
So my question is: Do you think this could have been a proto-type? The plowshare and cap are cast as one piece with a screw holding a stamped brass cross bar with rubber O-Ring behind that.
Question #2 Whose's brian child was it to use the Plowshare Cap and why? Please no guessing, looking for fact.
