There was a recent thread about WW II bunters where the 43 bunter was used for 1944 by grinding off the “3”. Did the 1945 ammo have a single digit HS also? That old thread also indicated that the 1955 cartridges had a single “5”.
This question is active on another Forum and concerns TW ammunition with a single “5”. Is it 1945 and corrosive or 1955 and OK to shoot?
