Have this very interesting box of cartridges, completely full. Believe it is from the mid-30s, and is special purpose target ammo, as the pics will show. Cases are nickel-plated, primers are the old, rounded type, corrosive, according to the box. Well, read the box and if you have any questions, ask away. Cartridge collectors guide I consulted listed these valued at $100-$200, I will sell these for $60 plus actual shipping.
