I've got two unopened boxes of ammunition, marked:
20 CARTRIDGES
NATO CAL 7.62 MM
BALL M59
LOT WCC 6005
WINCHESTER-WESTERN DIVISION
OLIN MATHIESON CHEMICAL CORPORATION
Trying to get some info on these, such as date of production, and current value. These boxes are unopened, and in excellent condition. Thanks for any and all help on this.
