Marek found me a sealed can (now open) with four of these like new time fuses. It can be set for up to a 22 second delay from the time the bomb is dropped. It uses a burning powder train for the delay action. Would this be the correct fuse to go on the Russian cluster bomb carriers filled with AO-2.5 bombs? Does anyone have any pictures of Russian bombs equipped with these fuses? I do have a few spares if someone wants to work a trade. These should ship anywhere in the world (disassembled) without trouble.
