I had a dig at an airfield near my home but didnt have much time
so two hours there. I only came up with a couple of items but need help to I.D them, One is a connection plug it is brass and has two prongs that are broken. It also has a hairline crack to it there was the rubber pad with it, it is 1,3/4" long x 1" wide.
The cartrige is aluminium 3,1/4" long x 1" wide the primer is missing. I also found a piece of molten aluminium these were all found behind a revetment, the piece of ally is really burned and could have come from an aircraft burning. hope you can help.
