Vintage Military Polish Army Aluminum Water Flask Canteen Retro Cold War Era. These canteens are preowned. They have some surface scratches, dents, stains, and wear. One is 1980. One is 1982, I think, it's hard to read. The words on top translates from Polish to English as Olkus Factory, and the date. Clean Aluminum 99.5%.  The 1980 one has WP stamped in neck. The other one has MON stamped in neck. One is worn on top more than the other one. Also one has cork type seal, and the other one has what seems like rubber type seal. The cork one has more stain on screw on area. They measure approximately 7 x 4 1/2 x 3", with lid on. I didn't find any holes, they still work. See pics for more description. Thanks for looking! (C4)
