Subject: [GreenKeys] Looks like Stroboscopically-tuned Teletype Baudot Test-Set

From what I can see in these ebay pictures this unit appears to be a 
stroboscopically-tuned distortion test-set for 5-level Baudot equipment...real 
Teletype engineering...all mechanical, electrical, no electronics.  I'll bet 
they didn't make many of these.

Of course I'm guessing from the labels on the control switches and the fact 
there's a little window at the start of the fifth bit that seems to be part of a 
rotating plate on the front panel.

Anybody out there actually use one of these in real-life?
