Vintage BOG Mfg. Double Offset Box Wrenches No. 1214A 3/8" 7/16" and 2428A 3/4" 7/8"
Good used condition with missing chrome. The 12 point box ends are in very good condition. Stamped "Chromium-Vanadium". (1E)
From the 1932 BOG Mfg. catalog: "The 15 degree double offset box wrenches have different opening each end. Box walls are extra thin and depth of opening permits their use on the most difficult job."
