4" adjustable WHO'S MY DADDY??

[phillie]

I have a 4" adjustable with no maker on it. There is an 0 on one side and 1/4 by 4" on the other. It came out of a shed of other vintage tools. Does anyone know the maker. Thanks

I am thinking Plomb, Proto or P&C. They are all related. I have had Plomb tools in the past with just a letter O on them and nothing else on them. Your adjustable appears to have a plain hang hole like early Proto adjustables. It may also be a early Japan knockoff
