Hotel de France, Chateauroux, Indre, France. +4038 Mr. Hancock from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} We thank you for your note of the 21st. re. the Telegage. We presume you will be able to prevent the air leaking occurring in the pressure line at the unions by using some jointing material to exclude the possibility of air entering there. It is rather unfortunate that you are having this trouble but we hope that you will be able to overcome it by this means. We agree that the hand pump is not the best possible job and have received a better model from Messrs. Claudel Hobson which is lighter and the knob is locked by a lock-nut. We also propose to reduce the knob width. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
