Trying to keep some 1960s junk going. Uses a long thin 1.5V motor so CD motors won't fit. A failed brush/contact. Before I randomly open another CD/cassette motor to rob a brush, anyone know the what the material is? All I've found so far is phosphor-bronze carriers with a brush insert, but the original is either 2 or 3 fingers conjoined, 2 on one side 3 on other side of the comutator, of a non-magnetic strip material, shiney material like tin, but obviously must have some spring and withstand spark errosion.
