Hello. There are two 6 Pr projectiles pictured here, both 43 dated. Why the different driving bands? The black one on the left is marked on the driving band; P 6PR 7CWT VI T 425 BS StC 8 8-43. The red one on the right (That cant be the original paint can it? It does look old.). It is marked on it's driving band; LOT 252 broad arrow , and then on the body above the band; SD / upside down V 582 / P 6PDS 7 CWT LVT / MC BS / LOT 252 9/43 . This should be an easy question for you guys. Thanks!
