OUR REF... WEB. 23, GUILDHALL BUILDINGS, NAVIGATION STREET, BIRMINGHAM. April 1st. 33. Messrs Rolls Royce Ltd., Derby. Subject:. Composite Steel Brake Drum. Dear Sirs, For the attention of Mr Hives. The enclosed re-print describes a brake drum, which we have developed as a result of the demand for increased brake efficiency, and which we find, after extensive tests, possesses the advantages claimed. We attach a full specification of the drum, and should be pleased to show you a sample. We should appreciate an opportunity of putting forward our pro-posal for a design to replace any of your existing drums, also to supply you with an experimental set. For this purpose we should be obliged if you would kindly let us have a drawing of your standard drum, with par-ticulars of any clearances between dust shields etc. Yours faithfully, For PRATT & MANLEY, W.E.
