The modification asked for on Bentley and 20/25 HP. flexibly bladed fans in Hs{Lord Ernest Hives - Chair}/Std.6/JH.19.3.36 should be incorporated on the Ph.III flexibly bladed fans which you are building for us. We are particularly anxious to obtain one of these to test, so that after it has run on the test bed etc., it can go on the next 15,000 miles test. Hs{Lord Ernest Hives - Chair}/Std. | ||
