For the attention of Mr. W.A. Robotham.

Messrs. Rolls-Royce, Ltd.,
Derby.

Dear Sirs,

Re 20 h.p. Telegage.

We are in receipt of your letter of the 13th inst., and note that the direction in which the air line connections on K.S.175 should point is 45° to the fore and aft direction of the car.

We think it would be as well for you to let us have another tank at your convenience, so that we can check the fact that we have got the set in our tubes correctly to bring the bell vertical, and to correspond with the datum which we have established on our previous drawing.

With regard to future tank units which you may call for to K.S.175, we have noted the action to be taken, and pending receipt of a further tank for checking purposes, we have evolved another unit for this installation,
