[GreenKeys] AB Drums

[teletypeparts at comcast.net]

Gary, 
  
They are hard to come by uncoded.  I have one on hand at this time.  There should be an uncoded AB drum in any 33 that was used with a computer.  Its the TWX and Telex machines that had the drum coded with the companies abbreviated name and city.
