I don't normally buy a lot of the newer forged alloy wrenches but I think The "X" logo wrenches are neat looking and the lot wasn't bringing much so I bid and got them. Last night when I was removing them from the pegboard I found the double open end ones had small W. W. Woolworth tags on them. They all look like they are NOS, never used.
The open ended ones are marked U.S.A. PAT. 97325 - X - ALLOY STEEL. The double box end is marked PATENT - X - 97325 / U.S.A. NICKLE - X - MOLYBDENUM
FrankLee - What size is your double box end?
