8/1/18 - This is an original box of vintage Winchester 9mm parabellum ammunition. The box is in tact and has an ink stamp for the lot number. The actual number is hard to read though and was a poor stamp. There are only 20 rounds included in the box - as shown in photos. The round are excellent, and this would go well as display with any vintage 9mm submachine gun. Could possibly have been made for United Defense Supply Corp's M42 submachine gun made during 1942-43.
