1938 Obituary 
We regret to learn of the death of Colonel A. W. Chadburn, V.D., J.P., chairman for over forty-four years of the Standard Piston Ring and Engineering Company, Ltd., Sheffield.
During that time, among his many other duties, he was personally associated with all the advances made and improvements in the design of piston rings from the plain Ramsbottom ring to the precision article of to-day.
Colonel Chadburn was a well-known volunteer, having been gazetted to the West Yorkshire Royal Engineers Volunteers in 1885.
