5 prong connector

Does anyone know what this was used for? It was included in a set for the E36 rangefinder. Seems like I've seen this for a battery connector of Russian electrical optic equipment.

Thanks,

The type of prongs look to me like a speaker connection from something in the order of a loudspeaker system or a radio.

The rangefinder set, which was a US bring back had this included. Might be communication wire? Either way it was in the case in 1944 when it was shipped
