Information from Scott Duff:

After Col. Guion took command of SA in July 1950, overhauled M1 rifles "were (hand) stamped "SA/JLG" on the stocks left side. A similar final inspection stamp was also used on newly made M1s when the production line reopened in the early 1950's. When the new M1 production began, use of the "SA/JLG" rebuild stamp ceased and was replaced by a rebuild stamp consisting of ""SA" often enclosed in a three or four cornered box. Many of these stamps also had a one or two letter code to identify the inspector who supervised the procedure. This "SA" rebuild stamp was most commonly applied to the left side of the butt."
