T.F. Welch Drill & Tap Drill Gage Rare!
This is a nice clean drill and tap drill size gauge marked "T.F. WELCH BOSTON" on one side, and "TAP DRILL SIZES" on the back side. It has numbers marked from 0-60 on the front side, and 2-56 to 14-20 on the back side also. T.F. WELCH BOSTON is a rather rare name to see on this type of gauge, the more common was the Starrett brand. This one is 1.7 x 5.3" long, and is in good++ condition with some minor wear, and scratches noted, no rust, no pitting, and no past owner's names. A truly collectible machinist tool!
