I found a concrete piercing fuze that I need help identifying. My theory...
Since the TM9-1901 Artillery Ammunition manual dated 1944 has no concrete piercing fuzes listed, I assume America went to war without one in its inventory.
TM9-1901 dated 1950 does list the M78 concrete piercing fuze. Apparently the M78 started out as the T105 before being standardized. The fuze I found has a different, shorter ogive than the M78.
Oddly enough this short ogive CP fuze matches the ogive pictured in TM9-1901 (1950). My guess is the M78 originally started out with a shorter ogive, they drew it up and put it in the manual. Then they changed the ogive, never bothering to go back and update the manual and drawings. Has anyone ever seen a short ogive CP fuze like this?
First photo - fuze on left is T105, fuze on right is the one I found.
