I got last year a 20 pdr HE shell which is not fuzes, since the Swiss Army used british 20 pdr ammunition just a few years it is very hard to find a No 257 fuze here. Therefore I am looking for a tecnical drawing of this fuze so I can gived to my friend, he will try the make some kind of a reproduction of this fuze.
Any help is appreciated.
