At the head of every letter written to us on the subject of a machine we advise that the engine number with serial letters should be quoted. The number and letters will be found stamped on the driving side of the crankcase just below the bottom flange of the cylinder. Police Registration Numbers are of no help since these are invariably allocated after delivery of the Motor Cycle from the Works. In all communications a really legible signature and the full address are necessary and important.

If a letter addressed to us is in reply to a letter received from us the letter reference, which will be found in the letter heading on the left-hand side, should be quoted so that the letter may be passed immediately to the the individual dealing with the matter.
