Seen at a local flea market today. a number of Richardson wrenches. I've not seen the name before but they do resemble Craftsman wrenches. I can find no further info on them, the back just says Drop Forged Tool Steel with a 900 series number depending on the size.
I see a Richardson patent from 1863 for the first ratchet wrench and on ebay is a bicycle wrench marked Richardson Chicago, it does not look related.
