Has anyone seen tools with the "Shell" name on them? This wrench has what appears to be the circle "M" of moore drop forging? And then the Shell name with a 751 in front of it. I believe this large Shell mark was done at the factory, and not in house. Also, it may have had another open end at one time, but not sure of that either. Any thought or Ideas appreciated. The size is 1-1/2" open end.
Thanks,
Wayne
