COMPRESSION IGNITION TEST UNIT. As requested during your visit yesterday, we send herewith blueprint of unfinished scheme LeC. 3011, showing preliminary layout of two stroke sleeve valve C. I. unit, to enable you to proceed with the two stroke No. 1. unit. In accordance with Rl/424.5.32., the cylinders are spaced 6.5" apart, and the 5 bearing crankshaft is held in a 4 cell cast iron test frame, similar to the four stroke unit LeC. 2735., the spread at the base being kept the same. H.{Arthur M. Hanbury - Head Complaints} recommends that the 5" bore and 6.6" stroke be adhered to. We are working on the sleeve mechanism and pump drive, the scheme for which will be sent to you as soon as possible to complete the particulars of the crankshaft. R/EYR.
