[GreenKeys] Unique Teletype

[Duncan Brown]

The tag on this unit identifies it as being from the Teletype Corp 
Museum (which was disbursed in the 1980s) and looks to be the item 
pictured in Teletype Corp Museum Book 9, page 05.  The Museum Book says 
they were produced from 1922 to 1930. (Replaced by the M15)
