Very Rare Western Electric 2A current Supply Set Loudspeaker Telephone Outfit

  

Vintage Western Electric Supply Set. Original wires with on/off switch. Output wire appears to have original string still tied to it. Both "Tennis Ball" tubes light up when powered up.

There are some disconnected wires in the back however I did not test any further. No components appear burned or missing.

Tag is marked "Licensed for use as only part of the Western Electric Loud Speaker Telephone Outfit" See last picture of red circled item for ref. This is a very very rare piece circa 1920's and is in very nice display condition. It appears to have been stored inside and has no signs of corrosion or water damage.
