R. {Sir Henry Royce} E. {Mr Elliott - Chief Engineer} Na. {Mr Nadin} Special Washers were ordered up on 10/9/13 to be tested.

Washers in lead, special fibre, and copper asbestos were handed to Mr Hives on 1/10/13. These were reported on by Mr Hives on March 13th, after which Mr Royce suggested that an ebonite washer might be tried. This was handed to Mr Hives on 18/5/14 and we attach herewith his report. A similar washer is also fitted to 58NA. {Mr Nadin} P. Wor. {Arthur Wormald - General Works Manager} Attached:- Wor {Arthur Wormald - General Works Manager} /EH2/C28714. | ||
