| +1677 Exptl. Dept. Hs{Lord Ernest Hives - Chair}/Bwg.{J. C. Bowring}27/KW. 14th March, 1935. The S.U. Company Ltd., East Works, Adderley Park, Birmingham 8. For attention of Mr. Kent. Dear Sirs, Will you please supply as soon as possible two more electrical pump units, wound non-inductively and coil housing step chamfered as before. We enclose drawing of our armature and shall be pleased if you will have two made and copper plated. With regard to the core, it will be necessary to chamfer this to suit the armature dimensions which are shown on the drawing. To deaden the noise from these units we have put packings to a thickness of .020 in the armature recess. Will you please complete these units, including black enamelling, and let us have them at the earliest moment. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
