Nice!
I think the Nickel/Molybdenum is considered an unusual alloy for tools, and as such is is a dead give-away for Bridgeport stuff.
Here's some no-name DBE's I've acquired, and the one had NiMo on it. Leads me to think it's Bridgeport.
I have an old wrench marked BHM in a stylized logo. It is a stamped wrench.
Any one know about these. Also an Old Maxwell-1 wrench.
I collect plomb tools especially 1/4" sockets and ratchets.
Is it ok to trade on the website?
