| X-185 Wor {Arthur Wormald - General Works Manager} /Mcr10/L29.4.15. R. {Sir Henry Royce} J. {Mr Johnson W.M.} c. 29.4.15. X.1309. X.562. X.185. With reference to your memo R15/IB22.4.15. Mr. Ellis reports as follows :- "*I will put in hand at once a Carpentier trembler "*action coil, the previous ones No.3307 and 3215 "*have evidently gone away on chassis. These were "*reported on Nov.18th 1909 along with the Castle, "*and if you remember they did not compare with "*our standard coils both in regard to speed, "*consumption (very heavy) and very noisy. "*In regard to the separate trembler coil, I have "*still got the one which was fitted in a smalk "*aluminium box and a separate coil, the two which "*were made combined have been lost or despatched by "*the West Garage. I cannot understand why this "*was discarded, I consider that there is no comparison "*with any of the other coils or any other make. "*It is fool-proof in regard to the turn of the screw on "*any speed and not limited to a 1/8" of a turn; consumption "*very low and regular, speed much higher and quieter, "*splendid on the platinums. "*Shall I rig this up with the trembler self contained "*or make this separate as before". Mcr. | ||
