Fowler Clarke - Electrical Engineer} 1/T. 20.1.25. in connection with the timing marking on the aluminium wheel in the above magnetos, this matter was taken up with Messrs Norths, who have now sent us a small segment cut from the wheel, showing what they propose. They state that the marking can be seen through the inspection hole much more readily than any other form of marking they have tried, and they would like to know if this will meet our requirements. We hand you herewith the small segment in question, and shall be glad to know if you agree. BY {R.W. Bailey - Chief Engineer} /C. [STAMP: RECEIVED DERBY] [STICKER: ENCLOSURE No 316 WJUSTSO] | ||
