Supro Information

There is lots of information about Supros and Valcos out there. These are notes for a couple lesser documented Supros.

The 1957/58 Rhythm King.

The 1967-69 S6699 / 62-9052

I have an Airline 62-9052, so these notes are specifically about it, but the Supro S6699 Statesman is nearly identical.
