I show the R^L Fuzes Percussion Mk 11 and Mk 111* used in Breech-loaded Land Service 20Pr, 12, 9 & 6 Pr segmented and common shells.
The fuze has a twisted safety pin and square hole at the top for the GS key.
Mk11 was introduced in 1873 and the Mk111 in 1887. I have no information on the Mk111* fuze. There was also a Mk 1V modification.
Note that the Mk111* has an extra 1 stamped and the modification date when the Mk11 fuze was modified.
