I had some adjustable wrenches with the three diamond logo and username alerted me that they weren’t wartime.
Post photos. I don't want to side-track Bill's pliers dating thread, but I'd like to see them.
It's almost impossible to distinguish pre-war from wartime Utica crescent-type adjustables (both webbed, both ALLOY STEEL, both had the < U > < TI > < CA > logos). They dropped the U.D.T.F. during the war (better said, sometime between 1941 and 1951), switching to UTICA. But both are acceptable in my opinion, since there is no evidence in the public domain on when exactly that switch took place. (Note that AA has the 1941 catalog and a 1951 catalog, nothing in between.)
The web panel and the < U >< TI >< CA > logo were gone by 1951, so postwar adjustables are much easier to eliminate.
Maybe Unaiu has information I have never seen. (EDIT: Did I miss a Tin Medic UTICA catalog drop?

) Maybe he will jump in. In the meantime, I'd like to see photos.
