| Y4077 Hs.{Lord Ernest Hives - Chair} from BY.{R.W. Bailey - Chief Engineer} BY3-P14.3.22. INSTRUMENT BOARD. GOSHAWK/11. SPEEDOMETER. Sg{Arthur F. Sidgreaves - MD}, from Sales, has sent us the attached pamphlet shewing Ripaults O.S. Speedometer. This appears to be a magnetic type and is therefore probably similar to the A.T. If you are interested in examining one of these instruments I would obtain one from Sales for this purpose. Whilst on Speedometers, I would like to see the inside of an Elliott and an A.T. at some time or other when convenient, as I wish to examine the mechanism in both cases. RECEIVED MAR 14 1922 BY.{R.W.
