Not a whole lot! Morse code training classes made use of a BD 57
switchboard, stations with a J48 key and headphones, a record player, a
McElroy Tape puller, and a Lon-Ga-Tone Automatic keyer, a TG 10 B.

The Lon-Ga-Tone keyer looks a lot  like the TG 10 set. It has two reels
for paper tape, a photo cell, main and motor on/of switches, speed and
PEC Bias controls, key/tape switch, and two other items, monitor and
volume, but am not certain if these are jacks or screwdriver adjustment
slots. It has 8 tubes and three transformers, T1, T2 and L 1.

This based on a line drawing and I have never seen one in person.
