Just an idle question really, but did all the Silverstones with the Albion gearbox (RBS to RES) have the outer primary case attached with the two studs between the engine sprocket and the clutch? My RDS, supposedly the Orpin w/c bike built by Peter Williams in early 66, has a similar case to the Griffons with the 1/4 Whitworth screws around the outside edge but with a casting change to accept the tach drive. Was this standard or something that Peter made up?
