Type 92 - Small Short-Delay Base Fuze
Use: A.P. projectiles for 57-mm tank guns.
Description:

Over-all length: 2 9/16 inches.

Maximum diameter: 1 1/4 inches.

Threaded length: 25/32 inch.

Number of threads: 9.

Construction: Threaded onto the base of the fuze body is a metal cap which serves only as a cover for the centrigual detents. Threaded into the forward section is the ex-plosive train carrier. The fuze body houses two centrifugal detents, a striker and a creep spring. The detents, fitting into a circular groove, hold the striker from the primer.

Operation: With centrifugal force the spring-loaded detents move out, leaving the stri-ker free to move onto the primer on impact.
