Calton, Fred, no “r”. Unfortunately, Keith sold out to the yanks several years ago and retired. Now they cost more than many people would pay for a guitar!
The first one I ever saw was yellow - most people back in the day had black cases although there were some blue ones made by/for Martin. The late Derek Brimstone turned up with it. I asked him where he’d got it as I was in the market for one and he would only tell me if I promised not to get a yellow one!
