Timer containing a “Kienzle”-brand pocket watch and battery. This simple design was the “standard model” of the BAS. For legal reasons, the detonating cap has been removed from the specimen exhibited here.
In this homemade timer-detonator system of the BAS activists in northern Tyrol, the detonator contact consisted of a screw usually placed at the 9-o’clock position.
