I saw them at the Miami Hamboree this year. They were being sold by a gentleman named Fred G. Schmidt.
His phone number from the flyer he was handing out is
954-583-1340, FAX 954-583-0777. The mailing address is:
Typetronics
PO Box 8873
Ft Lauderdale FL
33310-8873
The flyer doesn't show an email address.
Hope this helps!
