[GreenKeys] KPH Panoramic Pix

Steve & the gang -

   They are paper tape punches -  they punch 1/2" paper tape with the 
Wheatstone code.  Once the tape is punched, it can be read by one of the 
variable-speed tape readers to the right of the punches.  The punch & 
reader setup is used to key the transmitters.

   The paper tape can be spliced together end-to-end to make an endless 
loop, so that the transmitter will continually send out the same Morse 
Code message.

   The Wheatstone code dates back to the mid-1800s -  the spacing of the 
holes in the tape yields proper dot-to-dash and dot-to-space timing as 
long as the tape is moved through the reader at a constant rate.
