| X 8530 EFCS/AD. 28th May, 1929. Mr. G.R.N. Minchin, Messrs. Peto & Radford, 50 Grosvenor Gardens, London, S.W.1. Dear Mr. Minchin, Answering your M/S of May 27th, arrangements have already been made experimentally and will probably appear on production, for incorporating the red lamp in a grouping of instruments on the instrument board. The red lamp will probably be symmetrically placed near the thermometer instrument. Yours sincerely, | ||
