Norton 500 motor bike and side car ex military

1940 Norton 16h 500 with Watsonian side car.
A letter from the Norton owners club states it was allocated to the war department.
There is a brass plaque on the tool box that says Coldstream guards 2655206 m. Walton which may have been the rider.
Starts and runs well fun to ride tax and mot exempt in very good condition for age. Cash on collection with in 7days. Thanks for looking.
