Willy Wiley, former Pres of CT Valley Chapter had one dropped in his lap last year and is looking for advice to get it running. It appears to be loosely based on the 700 with an air cooled boxer engine in the back.

Just bought a '61 700 Sport Coupe and started the restoration. Solid, complete with original blistering 40HP motor. Gonna be fun!
