CHB/HD.{Mr Hayward/Mr Huddy} YOUR REF. 20th September, 1935. Messrs. Rolls Royce Limited, Experimental Department, DERBY. Dear Sirs, FOR THE ATTENTION OF W.A. ROBOTHOM, ESQ. Further to our conversation yesterday, we understand from Mr. Clay that all the pistons which are not considered usable for various reasons, have now been returned to us, and we think it is a matter for some comment that some of these are from deliveries which we made to you as far back as January and February. However, the following is an analysis of the position and the figures involved under the various headings. Total number of pistons delivered up to 18/9/35. 2,148. Total number of pistons returned 612. The analysis of these is as follows:- Returns due to revision of heat treatment 189. Returns due to revision of gudgeon pin fit 209. Returns due to request to machine gudgeon pin faces 37. Returns due to Rolls Royce own scrap 32. Returns due to incorrect test for gudgeon pin squareness 5. ____ 472. | ||
