| 5/10 As/West 8605/1 To B. from Sg. {Arthur F. Sidgreaves - MD} Copy to Nor.Ho. SY.C./ RV/ED. {J. L. Edwards} Hs {Lord Ernest Hives - Chair} /Wst. re Instruments. Sg {Arthur F. Sidgreaves - MD} 9/El.3.34 Thanks for E.4/HP.28.2.34. I am inclined to agree that the actual illumination of the speedometer on the Terraplane was a little on the bright side and I was more keen on the general idea of interior illumination than a close following of the Terraplane. I note all you say and shall be interested to see something of the schemes to which you refer when I am next with you. Sg. {Arthur F. Sidgreaves - MD} | ||
