| X5695 Roy.{Sir Henry Royce} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/RmL/LGS. 1.23. "ACROMETER". With reference to the information you have sent to us on this subject, we are considering the the one we have indicated in Messrs. Negretti and Zambra's letter. There is no reference to range and whether for hot or cold indication, however, on this list. The one we should have liked is the pattern A.350.N. in their price list. If this is unobtainable, we should like more information about the former. The range which would be the best for us would be 0 to 250 or 0 to 350 lbs. per sq. ins.
