For that 4th picture, that headstamp is for the Twin Cities ordnance plant in Minneapolis, Minnesota, for 1942.
You are single handedly going to lower the ferric oxide content of the soil in that area ! Great finds. Gaines
Nice finds! May I ask where you found them? Just the region will do as I don't want you to think I'm stealing your detecting spots
Mühlheim am Main Frankfurt. Please, by all means have fun in this area! Maybe we could meet up for a spot of MD'ing if you come to FFM?
Yeh! Had found two of them, I think it was from some allied aircraft in the area, as Hanau area was heavily bombed during WW2
