Hello out there !!!! I present you my newest Fuze, it is a German bomb detonator Z 17 Am. with a running time of 2 - 72 hours. Not to be confused with the Z 17 Bm. which has a running time of 120 minutes. The optics of the 2 Fuze are exactly the same, only painted in the colors AM = green, Bm = dead. This Fuze was built into German aerial bombs, which then served as a booby trap. See image. This Fuze is super rare, even in this condition. Harry
