Definately a 35,judging by the starter it appears a model 1 just check the serial number,should be around 1 to 3,000? The series 1 did NOT come with the magister secondary it was added later,so no hole should be in the cowl.if its a later model any no from 3000 to 20,000 should clear up its accuracy.as for its worth,who knows,there aint many left and not collected often by non SB enthusiasts.50 to 80 id pay.As for Blumblys beastie,is a damn shame!I really need another throttle control frown Just because it aint worth much dont mean it aint RARE....:(
