https://cat-uxo.com/explosive-hazards/fuzes/no-117-fuze relates to the No 117 but on checking the rest of the site there are 27 pages of fuzes, 26 of them with 28 fuzes on each, from artillery and mortar fuzes to mine fuzes and fuzes used with booy traps. Spotter has been a contributor to that site. I found it quite interesting. It seems to relate mainly to modern ammunition. I did not find a direct reference to the No 119 fuze or to the M54 fuze, examples of both of which I find on my favourite beach.
