Fuse Dopp Z 91
Double effect 45 mm fuse, without delay, Model 1891 brought
back by Pte Ned Burton, RGLI.
This double-effect fuse included a classical percussion system
in the tail, and a single rotating disc time system. The graduation
figures from 3 to 44 seconds, and with a cross for a pure percussion
function, were engraved on the upper rotating cone.
Fully made of brass, it had a security pin (two rods) blocking
the time system concutor. The arming system of the percussion
device was quite special, based on the movements of a tube sheltering
the starter-bearer, blocked by a powder grain ignited by the
concutor at the shooting time, and therefore without any stem,
unlike most of the German fuses.
That fuse mostly equipped the projectiles of the 90 mm guns
(explosive and shrapnel shells)
