| Extract from "The Light Car and Cycle Car." Oct, 28th, 1921. WHAT WAS THE SECRET of the TALBOT-DARRACQS? How it was possible for a 10 h.p. Engine to maintain 90 m.p.h. over a distance of 200 miles. Condition after the Race. - These marvellous little engines appear to be everlasting, for even the valve clearances had hardly altered after the 200 miles gruelling, while the exhaust was as clear of smoke and the compression as tight at the end of the race as at the start. MORAL: Follow Sunbeam-Talbot-Darracq EXAMPLE and use WELLWORTHY patent Universal radially direct pressure PISTON RINGS. LYMINGTON, HANTS. Handwritten notes: X741 What about it for Soo.
