Several years ago on the way to SLICS I picked up this USC Co. 38 Spl draw set at an antique store. It came in an USC 32 Long Colt box. (After Winchester acquired USC it was not uncommon to see older USC boxes used to store draw sets and partial draw sets of cartridges and bullets and other small parts and pieces,).
The side of the box is marked 38 S&W Special .045 Stock 7-10-24. I assume the “.045 stock” refers to the thickness of the brass sheet used to make the 38 Spl case. Was 0.045 inch stock the standard thickness for starting this draw process or was this some type of experimental draw?
The draw set itself contains duplicate pieces as well as several pieces that had been sectioned. The last draw piece was headstamped but didn’t have a flash hole in the primer pocket. Several of these last draws were headstamped “U.S,C.Co 38 S&W. SP’L.” and others were headstamped "U.S.C.Co.38 COLT. SP’L.
Also in the box was a Tool/Gauge? It is a thin “C” shaped piece of steel with an inside measurement of 1.2075".
Whether intended or not it is the exact length of the second to last draw piece (the one before the rim and headstamp.
Why would a gauge be made for this piece in the draw process?
