Has anybody had one of these?

[Michael Hogan]

Here is an interesting item from a 1938 music store catalog. I had not seen one before and was wondering if any survived?
Does anyone either have one or has anyone used one? Very limiting I would think.

Ahh, right . . . . the one with the volume and tone knobs. I think there was a long ago thread on the forum about those. I did a quick search but didn't come up with it. I knew a guy once who had lost his left thumb, and tried all manner of ways to fit a bar to his finger. This would have been the ticket.
