| I am hunting out some figures which I will send to you in a few days' time; they may interest you. I noted with decided interest (at the Show in 1923 I think) that Delco had a practically closed circuit coil. Probably you are aware of this. Very truly yours, E. {Mr Elliott - Chief Engineer} O. {Mr Oldham} Turner. | ||
