This was made from combat debris of World War I...The Great War...The War to End All Wars...but realistically, just World War I. It sat in my grandparents basement in a backroom for decades. I ended up with it somehow. An attempt to bring some sort of "normalcy" to a war souvenir. The inscription is meaningless to me and to Google. It says:
O.F. 18 Pr
That's engraved on the shell casing which is about 6" high, perhaps a 40mm shell. It's mounted on a small stand and on the brass plate that's on the small stand it says:
THE SHRAPNEL STAND
Colonial Fixtures, LTD
The image below is a detail of the 2" clock that is mounted on the round. If anyone has a clue about any of the engravings, I'd really appreciate it if you'd let me know! Thanks!!!
