Dear Davie,
Surprisingly clean isn't it. Thankfully the timer or impact is not present! Load could well be though!
Two years ago, someone proudly presented/gave me something saying that "they knew I would be interested". It turned out that it was a 6" artillery shell from France brought back by his Gradfather in 1945. It had been fired, so G O D knows how it was come by! Timer mech. in place, and in VGC, and all the ID numbers on it, but I didn't quite like the 'white' at the timer/casing joint... any hoo, took it, wrapped it carefully in a spare jacket, and bunged it in the back of the L/R, and placed it safely in a remote corner of one of the fields until the Bomb Disposal bods were back in the area! (A WW2 experimental range is not very far away, and the Spring tides have a habit of turning 'things' up every year! - together with some impressive 'bangs' when got rid of!). They were quite surprised when I presented the item to them, and were most admiring of it... "that's nice", one said!!! So I left them with it/to it, and was glad to get rid of it!
Regards, Bernard
