[Milsurplus] AN/GSC-1 morse code trainer

[Hue Miller]

I have a McElroy built, GSC-1 morse code training 
appartus. This is in a travel-able carry trunk, operates
off 12/24 dc or 120 ac, has 4 keys left out of 10 
original. I dunno yet whether i want to keep it or 
auction it or??? Does this unit light anyone here's 
fire? The category of "morse code training devices"
is, i feel, a real interesting one, but i maybe should
be narrowing down my categories. -Hue Miller
