| To Hs{Lord Ernest Hives - Chair}/Wst. W.S.T 6-500. Dor{Mr Dorey}/Cdy.1/EKB. 24. 3. 36. With reference to Hs{Lord Ernest Hives - Chair}/CAP.12/JH. 16. 3. 36 regarding the installation of type R.868 Integral Screened Sparking Plug, we have inspected the installation of these on the Merlin-Horsley with the streamlined exhaust manifolds in position, and there appears to be no foul. Accessibility will appear to be as good as for previous types. We should, at any rate be glad if you could forward us an actual plug when one comes into your possession. Dor{Mr Dorey}/Cdy. C.L.S. | ||
