I have a pair of planters made from the brass end caps of a pair of Shillelagh ATGMs from my M-60A2 days.
I ended up with my Grandpa's lamp he made while touring in the Pacific during WWII and Korea as a machinist/Bosun's Mate. It's turned out of different size brass casings.
It's also hand engraved with the ports they visited during his service.
And it still works! Priceless. d:^)
