This is a Whiskey Tumbler crafted from a fired 40mm Bofors Anti-Aircraft casing, holding about 133cl of your favourite drink.
The primer tube has been removed and the hole plugged with brass. The whole tumbler has then been polished and lacquered.
Now available with the top part of the shell casing for when the tumbler is not being used. The top part has a 3d printed head in it, and a locating ring at the base.
A variety of years are available. If not requested before shipping, I will ship any relevant tumbler.
