The very best thing about this unusual telephone (besides the fact that it is in remarkable condition) is the original advertisement that shows this exact telephone. It isn't likely that anyone today would remember or have any idea that this telephone existed, but if you will look at the ad first, you will see just how special and how rare this telephone is. It is a Garl Electric Company six-point intercommunicating desk set. This system accommodates connections between any two telephones and any numbers of pairs of telephones on the same system and allows them to converse simultaneously without interference. The transmitter is a granular carbon solid back, and the receiver is a unique double pole outside terminal receiver. All contacts and springs are made of German silver.

Original coil and wires are in the base, everything is there except the inside of the transmitter is empty. You would never know it without opening it up. Size 12" T.
