WW1 Imperial German Kugel Hand Grenade This is a 1 piece resin replica of the WWI German Kugel Hand Grenade, model 1913 Aa. The "Aa" stands for Ältere Art ("Old Model"), it was the first and most complex of several designs of this type. It was cast from an actual demilled grenade. The body and fuze are cast as one piece. It is a good alternative to carrying your expensive and heavy original into the field, or an excellent display piece. The grenade was cast in a silicone mold so it holds all of the detail of the original. It is cast in a black resin and coated with a metallic filler, for a metal "sheen". TO WHOM IT MAY CONCERN. THIS IS A RESIN PIECE, IT WAS NOT, NOR COULD IT EVER BE CONVERTED INTO AN EXPLOSIVE DEVICE, IT IS PLASTIC. IT COMPLIES WITH CALIFORNIA POLICIES REGARDING THE SALE OF GRENADE REPLICAS!!!
