Dear Sirs, With reference to your letter of the 20th.inst. we note that you require us to supply one Electric Rev.Counter and one Magnetic type, but before being able to proceed with these we require the following information. 1) Do you want the Electric Rev.Counter calibrated .7916 engine speed, or half engine speed. 2) Particulars of coupling to where the Generator has to fit on to the engine. (This will also apply for the A.T. Magnetic instrument, for the cable drive) [Handwritten note:] x 56967/11 S Smith & Sons Cricklewood 3) Rotation of driving spindle. [Handwritten note:] Anti-Clock LOOKING AT DRIVE END On receipt of the above information samples will be immediately put in hand and sent for your approval. We take this opportunity of expressing that we trust you will look favourably on the magnetic instrument, as on the Electric Rev.Counter side of our business our orders are far in excess for Aircraft to our production, as if quantities are involved in this enquiry it will be easier to produce this for you as a Magnetic instrument. Always at your service. Yours faithfully, for A.T. SPEEDOMETER CO., LTD. | ||
