Ah ............. my first keyer came from Bell Labs! Funny round things in 
it. Had 3 leads and a tab on the funny case. Used a mercury wetted relay in 
a great big tube like a shot gun shell. Gee, I wish now I had that 
schematic! It worked great and was all scavenged from boards at work. I 
wonder what I used as a paddle? Don't remember, maybe my bug or a couple of 
J-38's base to base and vertical ? Talk about an interesting build, that was 
IT !!

The must have been NPN as they were everywhere then if I remember right.
