Parts for RBS Silverstone gearbox

[Colin Sparrow]

I have had an email inquiry from Thierry Chaballier in France. He is looking for parts for the gearbox of his RBS Silverstone. He's sent a picture and it is the 5-speed 'box based on the MX1 Challenger item.

Does anyone have any idea where he might find parts? If so I'll put you in touch with him.

Bit of a long shot, I know...

Met with Thierry at Dijon a couple of years ago. Same gears as the Royal Enfield Super 5 if I remember from the 60s, so maybe Enfield dealers in France? Not sure if Hitchcocks have any spares but worth a try. Dogsbody

Having told Thierry that the general view is that parts are unavailable for the early Silverstone 5-speeder, he's now said that he could get by with a 4-speeder.

So - has anyone got an MX3 "kidney" box or an MX4 cam-barrel box for sale?
