Coverley - Production Engineer} STAMPED: ORIGINAL STAMPED: RECEIVED 29 MAY R11/M28.5.31. X7310. X523. 45HP. - DOUBLE TOP. This should be ready for converting to electrically controlled friction type in present box in the course of a few days. It promises to be simple and robust, and workable with a two speed box; if good we can redesign much simpler and lighter. R.{Sir Henry Royce} | ||
