I have one that we use to make plates for a blind bowling tournament. It was sold by Scott for their manual pantagraph about 15 years ago. The main problem that we had with it, was that the letter wheel would get out of sync with the embossing wheel. We would take the gun with us to the tournament and do a test strip which one of the participants would read and confirm that it was in sync. The gun allowed us to emboss the braille lettering on the trophies at the event.
We also used it to mark the top front of the door key cards for the hotel that the participants were staying at.

Thanks for the info. I'll update the thread as needed for others.
