USA WWII Pressure Firing Device M1A1 Complete, Inert.

I say 'complete' because it was used like this, in fact the earlier models have no hole for screw the prongs. I have seen original untouched boxes with devices with hole and no prongs at the box, as prongs were an option depending the using you wanted to give to the device. The primer is still in place, but inerted, the screw is damaged, as made of zink sometimes they brake, so, it is priced accordingly. I remember 15 years ago when this items were everywhere in their original untouched boxes and nobody wanted them..... Try to find one today. This was used for booby trap the MKII grenades and the TNT blocks. See last photo for reference. Only the device is for sale, the inert grenade and empty TNT blocks are only for reference. You can find the green 1 Pound TNT blocks for sale here also. I will send the device dismounted in a box.I combine shipping ALWAYS!!!Shipping Costs:-Europe: 12,50 €.-Worldwide: 16,50 €.-USA: 24,00 €.
