Hello all. I just stopped by my local antique store on my way home from work to see if they had a leg vise on hand. Sure enough the owner did and I ended up leaving with a rusty old vise that he says he got up in Boston bar, BC. Perhaps it is a remnant of the gold rush that happened in the mid to late 1800 in BC. Any who. I brought it home and quickly disassembled it and started at it with a cup brush. The only mark I found was on the female end of the vise thread. A letter stamped M or W. Can anyone help me I'd this vise? Sorry if my photo size is too late. I have no idea how to reduce.
