Mike Guffy is selling these. I bought one, and I'm building now. They are early 60's, cast aluminum frame, made by the Phillip's Conveyor Company of Memphis Missouri. They were called, Argyle Cub, JoyRide, and Dinky Cycle. It's a neat little fold up mini, originally produced for pilots to take along in their airplane. Here is a link to the post.
