don't have a ruler, so guessing about 5 or 6 inches wide, about 3 inches high. If I find a ruler, will post more accurate size. Made of metal. Not sure what kind, but it goes off when going through a metal detector.
Everytime unique auctions come around like this one, i never have enuff credits....is it handmade by yours truely? It looks like you are making it in your basement from some old shells from the range or private property from the pic....i wanted to know so if more can be made...whens next auction on one....love it!!!!
