Complete novice here…I have a 20mm Cannon (?) shell in an empty brass catrtridge case dated 1943 which I inherited from an uncle.
He always told me it was a cannon shell from a Spitfire.
The shell is painted black, in good condition, with a flat tip.
It is stamped WMC-3
3 - 43
It has a 5 or 6mm copper ring around the base with rifling grooves, the bottoms of which are unbroken and level with the outer surface of the ring.
My question is, is this SAFE? It has sat next to a coal fired hearth for some fifty years, so I hope so!
Has it any value, moneywise or to a museum?
Also, I have the rear magazine cover from a machine gun of a Junkers 88 that was shot down over Dunkirk, as well as other relics. Is this likely to be of interest to a museum?
Any help gratefully received.
