[GreenKeys] Stock Ticker

[Duncan Brown]

I don't  believe that it is Baudot/Murray/5-bit.  The mechanism is very 
simple, like the early stock tickers. I don't think it could be 
converted to 5-bit. (In the 1950's -60's they did switch over to 
Teletype Corp M15 & 28 machines.)

Enclosed is a copy of a printout & photo of the mechanism.

Have fun,

Duncan
