I have heard tell here and there that Edison, and possible some other companies, produced 2/4 minute conversion kits for the Triumph model A phonograph, but I have never seen one, and I'm not sure I know anyone who has. Can anyone out there confirm the existence of such a beast? If so, have you ever seen one for sale, and what did it go for?
