Picked up another 10" today. This is my second.
I would gladly trade one of them to any of you guys out there in Heller Bros Masterench land who has a duplicate 14" and needs a 10".
Also, we've noted the forged-in "7-11" and "41" marking on the flip side before, but I just realized that I don't think we've figured out what it signifies. Despite it being added to the die in the same or similar format as the patent dates found on the other side of the older wrenches, it's not a patent date. 7-11-1941 is not a US patent date, anyway.
Just a wild guess for everyone to think about, maybe this signifies the metal alloy, or the hardness/wear-ability of the finish? Might denote a proprietary formula?
Chromium 7-11 and Vanadium 41 aka "chrome vanadium"?
