I'm new here and though I'd contribute some pics of my collection of ordnance. I'm not skilled with a camera so the pictures are a bit blurry.
First picture shows 105mm artillery shell, 1907 Scoville shell, MG42 belt (casings are modern), 2 army surplus hand grenades, 6 pounder APCBC shell, 37mm shell, and 2 no4 spike bayonets.
Second picture (sorry for blurriness, I'll try to get a better one) shows a 5cm naval flak shell and a 155mm artillery shell. The 155 is very heavy so I have to keep it in my garage.
Third picture shows (from left to right) 6 random casings, 37mm shell, 40mm casing, 6 pounder APCBC shell, 1907 Scoville shell with timed fuse seperated, and 105mm shell.
