| *x3199* To Mr. Coverley. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 6/T12.12.18. X 3199 X 3129 X 2512 X 3129 RE CONDENSERS FOR IGNITION EXPERIMENTS X 3199 Will you kindly have made up with all possible speed, four more small ignition condensers similar to those already made. These new condensers should be made of the good quality thinner mica of which we have already had two made, one of which appears now to be lost. We cannot specify the number of leaves but we can specify the condensers by their thickness when built up. We would like the condensers to be according to the following table:- No. Depth. Remarks. 8. .500" Suitable for insertion into the condenser box of the aero ignition 9. .750" Ditto. 10. .750" Suitable for attachment to the R.R. chassis ignition in the same manner as the one fitted to 7 C-A. {Mr Adams} 11. 1.00" Ditto.
