Instructograph! I'm 99% sure that's what it is...I did a google search, and found some pictures. His is the electric model. I haven't seen it in probably 20 years, but I remember very distinctly what it looked like. I remember the big knob. I can also remember pretty clearly the musty smell when you opened it lol. Next time we go visit I'll see if he has it somewhere accessible and take a picture of it.
I also remember he had a big telegraph key...great big chrome thing with a red knob. Came in it's own storage/carry case that opened on the end. I think it had some sort of green fabric lining. I remember it having an oval metal tag on it with a dragonfly or something like that on it. I seem to remember it being more complicated than his other one. Going on some very old memories here...
The sounders he has are pretty old I think...1930s maybe? He's got one on a shelf in his office at home.
