G.{Mr Griffiths - Chief Accountant / Mr Gnapp} Cussons Ltd., Technical Works, Lower Broughton, Manchester. Dear Sirs, Re Optical Indicator for R.R. Eagle Engines. We shall be glad to know, with reference to our letter EFC4/T27.10.17, concerning your optical indicator, if you have yet been able to do anything in the way of scheming out a rig for supporting this on our engines. We are fitting up for test at the present moment, a Mercedes 260 HP. engine taken from one of the Gotha Biplanes, and we think it would be interesting, if possible, to arrange to indicate this with your indicator. This would be a suitable engine on which to gain experience on the handling of the instrument. Yours faithfully, | ||
