[Rolls-Royce Logo] X4284 b CC Mr. Belnap Mr. Nadin Oy8 - G 3821 August 3, 1921 Dear Hives: X.4284 Re: Delco X.4275. Your letter Hs{Lord Ernest Hives - Chair}3/LGS.6.21: We have received prints from the Delco people of ignition parts which they propose to supply us. They are - (1) single ignition head to clamp down in the position of our contact breaker housing; the manual advance being by a spiral spindle. (Print X-13670 is enclosed) (2) Coil for above. (Print X-8126 enclosed) (3) Dual ignition set of their "magneto replacement" type as used on the Pierce-Arrow and other cars. We have not intended to bother with this, as we anticipate that by the time we are in a position to use Delco outfits we shall have abandoned the magneto. The device is illustrated in the enclosed print X-9845. It will go almost without alteration in place of our magneto and of course has an automatic advance. We have still to obtain from them a suitable generator and starting motor. We find that a 5 1/2" generator can readily be mounted in place of the magneto and shall get one suitable for such a mounting from Delcos. The motor will be of the type suitable for the present drive, similar to what Bijur have supplied, since to incorporate a flywheel drive experimentally is a big job, and the Delco type of starting gear is particularly noisy. | ||
