After National Service in the Royal Air Force Harry Woolridge applied for a job in the Service Department at the Triumph Engineering Company, and was lucky enough to be selected. Thus began a working relationship with Triumph and its motorcycles that would last thirty years: an experience Harry says he would not have missed at any price. After a few years in the Service Department, Harry joined the team in the Experimental until he was promoted to the position of Assistant Quality Control Manager. Later, in a reshuffle of titles, he became Inspection Foreman for Motorcycle Assembly and Production Development. With the formation of the Meriden Co-operative, Harry served as Warranty/Service Manager until the factory closed in 1983.
