That maybe a Bridgeport Hardware wrench ? They put both sizes on some of their wrenches.

EVILDR235 is correct Bridgeport Hardware and the trade name for those wrenches is Pyramid.

Thank you and EVILDR235 for the info. Have any idea of the time period? or link to an online catalog?

Don't know an exact time period but I would guess 50's-60's give or take. As for Cats. http://www.toolarchives.com/
