Very cool insulator go-with -- A World War 1 vintage military telegraph/telephone set. (two units) This is new old stock and was never used -- in excellent condition. One if the units still has it's original cardboard box (box is pretty brittle and fragile). The leather and workings are in excellent condition! Each unit has a telegraph key, a mouthpiece (microphone) and an ear piece (speaker). There is also a grounding wire to allow a one wire system. Another view [id=398363654]

Imprinted on the leather cover is "Service Buzzer, US Army Model 1914". It appears that all the parts (screws, levers, nuts, switches and adjusting tools) are present. Dimensions: 7-1/2" by 5-1/4" by 3-1/2".

Take the pair for $200 plus actual shipping or $120.00 for a single unit.
