Typical WW2 era U.S. military contract 12 Gage shotshell packing with a 25 round box wrapped and sealed in a heavy brown paper type material.
Face of the wrapping is printed with
SHOTGUN 12 GAGE
AMMUNITION LOT W.R.A. 22219
WINCHESTER REPEATING ARMS COMPANY
DIVISION OF WESTERN CARTRIDGE COMPANY
I believe that Winchester provided many different loads during their WW2 contracts:
Number 7 1/2 or 8 for use in training gunners
Number 4 shot for varmint or predator control
00 Buck paper case for trench and riot gun use
00 Buck brass case for trench and riot gun use
Usually the outer wrapping is the same as the box markings if it is the “generic” black printed on natural color box, instead of commercial style colored boxes. But, the generic box markings usually include the shot size.
Obviously, the easy way to find out would be to open it up, but my collecting habits prefer to leave sealed things sealed.
Can anyone ID the contents from the lot number?
