X1812 Dear Sirs, Referring to a memorandum No.2507 which was addressed to you on the 2nd June '21 by your Inspection Department, I am now sending you 13 plugs, viz:- 6 (marked M on the side) for Magneto 6 (marked B on the side) for Battery 1 for dismantling and examination. I shall be interested to hear from you in due course whether these plugs have proved to be as good as the makers claim them to be. As explained to Capt. Burt, I am in a position to deal with the patent rights of these plugs for the United Kingdom and the British Colonies, either by way of sale of patents or by way of supplying the plugs to your firm exclusively, whichever may eventually be determined. Awaiting your news, I remain, Yours truly, George Roberts | ||
