Rebuild stamps

[Richardrose]

Hi, I have a fine Winchester M1 Garand stock on a rebuilt 1943 SA rifle. It has been through 2 rebuilds I believe. The stock is marked ""AA''and ""AN'' and has 3 letter P's . What I would like to know is what time period Anniston used the different letters. I'm guessing one before Korea and one after?
Thanks,
Rich

This may answer your question. http://www.americanrifleman.org/articles/2015/12/10/from-the-american-rifleman-archives-in-the-system-m1-garand-rebuilds/

Augusta Arsenal—"AA"—Typically with a letter suffix (presumed to represent the inspector who supervised the overhaul). Later a number suffix (typically four digits) was sometimes added. These markings may be found stamped on the either left or right side of the stock.

Anniston Army Depot—"AN"—Often followed by a letter suffix.
