This is a very rare and odd camera equipment: A Leningrad camera with remote firing device. No data is known about the equipment. The set comes complete with two battery fountains, the receiver, a special firing relay and the transmitter. Everything in contained an elegant case The control has a “РЗФ” logo (RZF) probably, Radio Zavod F? It is very interesting to note that the firing relay also acts as the receiver antenna. Probable manufacturing year 1963. Help on complementary data.
