    What Is Heat Lot Number??

      What Is Heat Lot Number By Scott Duff   Another factor (in addition to drawing numbers) used in the identification of Springfield Armory manufactured receivers, barrels, and bolts is the “heat lot” number. This is an alphanumeric code used by the Armory to identify the discrete lot of steel from which these three critical components were manufactured. Springfield Armory stamped the heat lot of the batch of steel used in the manufacture these three components in a location near the drawing number. The identification of the lot of steel used in manufacture of a group of components could be very important from a manufacturing perspective. Should a metallurgical problem…

    What Is A Drawing Number??

      What Is A Drawing Number??   An understanding of the engineering drawing numbers which were stamped on some M1 parts is necessary in order to fully comprehend the evolution of those components. For example: A hammer may be marked C46008-2 SA. The “C” designates the physical size of the drawing. The “46008” is the engineering drawing number. The “-2” is the production revision to the drawing. And finally, the “SA” indicates that this part was manufactured by Springfield Armory. The first production rifles manufactured by Springfield Armory were marked with an engineering drawing number on virtually every part which was large enough to be stamped—and even some that were…

    What’s a “Tanker” Garand?

      What’s a “Tanker” Garand? By Walter J. Kuleck, Ph.D.   The “Tanker Garand” is a “misnomer.” During WWII two separate prototypes were developed for paratroop use. The first was the M1E5. The M1E5 had a short barrel and a folding metal stock. It was developed and tested in the Summer of 1944, but then abandoned because of the loud report and large muzzle flash from the short barrel. In the fall of 1944 the Pacific Warfare Board ordered a test quantity of 150 M1 Rifles to be shortened and tested for jungle and paratroop use. These conversions were rather crudely done in the Pacific Theatre of Operations, either in…
