We have two spare A.T.instruments for the Bensport chassis with slot edge illumination instead of the now standard glass edge as shewn on drawings DB{Donald Bastow - Suspensions}93 and DB{Donald Bastow - Suspensions}87. The numbers of these instruments are, rev counter G228 and speedometer G441. Will you please arrange to return these instruments to the A.T.Speedometer Co., for modification to the standard type as shewn on the above drawings. We require the rev counter to read dead correct to 1% fast and the speedometer to be calibrated for 797 revs per mile with the scale reading exactly 5% fast at 90 M.P.H.
