1920s Direct line telephone/intercom
Hi
I've bought an antique intercom.
My question concerns getting them working!
I have read that all is needed is a multi-core cable and a 9v battery.
Does anyone recognise this set (they look identical/similar to others I've seen on the interwebs) and could advise further?
Thanks!!
