I posted a short while back about the Tomahawk wrench set and its distinct similarity to the 40's-50's Barcalo-Buffalo wrenches. I have completed two sets of Barcalos, giving one to my grandson. I am two wrenches into my third set. Bought this Barcalo and an Arrow wrench yesterday, same size, and brought the Tomahawk in from the garage for a "family photo". Evildr235 mentioned Arrow wrenches and I said I had never seen one - til yesterday.
The Barcalo has remnants of a thin chrome plate, The Tomahawk is probably cadmium, and the Arrow wrench has most of its chrome. Other sizes of the Barcalo set appear to be nickel plated.
