| INA.618. 1.4.19. H.H. Mr. Moon. from BY/HBO. X. 2512. BY/HBO1/WW1.4.19. c. to EFC. c. to O.O. c. to Mr.Coverley. c. to Mr.Brock. X.3129 - RE CONDENSER FOR BATTERY IGNITION - SEC:7370. Herewith L.O.P. F.7181 and complete set of drawings for the above. Will Mr. Moon kindly fill in the bar sizes, etc., and pass same on to the Order Office. This is the final issue with the exception of the following drawings which will no doubt be altered:- F.7172 - Condenser Casing. F.7171 - Condenser Connection. F.7170 - Condenser Connection. We shall most probably have to alter the depth of cover, at present it is shewn as 2.060 I have instructed the pattern Shop to make this cover ¼" deeper, so it would not interfere with the ordering of castings.. The reason for querying the above is due to not being able to definitely settle the thickness of the condenser. Will Mr. Clark kindly let me have the thickness as soon as possible. It is essential that 6 sets should be produced as soon as possible, apart from what the Experimental Department are making. BY/HBO. | ||
