1922 Model 9 Norton

This 1922 Model 9, fitted with the optional Philipson's pulley, was spotted at Brooklands last April.

Martin: "Simon and I both think this Norton is 1922, not 1921, particularly if that's its original engine, as engine 4200 dates from November 1922 when the surviving records start. Also the Philipson pulley has a visible date of 1922, and the frame has sidecar lugs and the final pattern of belt drive footrests with a wiggle to miss the brake rod."
