I’ve recently acquired this vintage Craftsman adjustable wrench and really am impressed with quality and build quality. The only information I can gather on the history of this tool is from the amazing Alloy-Artifacts website. They estimate the wrench is of 1950s vintage but are unable to identify the maker whose manufacturer code is a Y-circle? The code appears on a Dunlap 8” adjustable wrench of slightly differing design. Any input on the identity of this specific manufacturer would be greatly appreciated, thanks in advance
