(Note- this refers to the early (circa 1941 or earlier) Cartridge, Rifle Grenade Caliber .30 M1, not the later M3.)
Note the changes in labels just in these three consecutive lot numbers with or without information on the powders used, reference to rod length, sequence of the information and fonts.
Rick L. asked me to post these and ask if anyone has images of other boxes of the Cartridge, Rifle Grenade Caliber .30 M1 from earlier or later lots than these.
Lot 11 (Headstamp- RG FA 40)
Lot 12 (Courtesy Hackely, Woodin & Scranton, Volume 1 P. 161)
Does anyone have examples of other lots of these?
