  The Minolta Junior B.C. is a flashgun for big old flashbulbs. An adapter for modern small bulbs was available. 'B.C.' means 'battery/condenser'. That means that enough current for flashbulb ignition is drawn from a capacitor loaded by the 22.5V dry battery. The flashgun has a collapsible 13-lamellae reflector fan. On the back is a small analog calculator for computing an exposure parameter (probably the guide number) which is depending on lamp-to-subject distance.
