From the Website http://alloy-artifacts.org/barcalo-buffalo.htmlBarcalo probably began producing alloy steel tools in the late 1920s. The earliest production used (and was marked for) chrome-molybdenum steel, but probably by the mid 1930s some chrome-vanadium tools were being made.By the mid to late 1940s most of the tool production had shifted to a "special analysis" steel, most likely a carbon-manganese alloy similar to Indestro's "Select Steel" or Danielson's "Controlled Steel". In ...this post-war era the only tools retaining a high-grade alloy were the combination wrenches, which used AISI 8645 steel branded "Barcaloy"See pictures for look of wrench. Has nicks on it!
