ORIGINAL Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}4/LG8.9.28. Y4332 14.7 COTTIN DESGOUTTES We tried one of these cars in and outside London. It was a demonstration car and had done 10,000 miles. It purported to be exactly the same car as is being marketed by this firm for 1929. The engine dimensions are :- 6 cyl. 63 X 90 i.e. 1683 c.c. side by side valves. The chassis dimensions are :- Wheelbase 10 ft. Track 4 ft. 7 ins. Turning circle 44 ft. Weight of car complete with 4 seater Weymann body 27 cwts. The car was fitted with Houdaille shock dampers at the rear, no dampers in front. The general performance of the car was poor as can only be expected from the power weight ratio. The steering was better than that of the last Cottin we tried as it did not actually wobble, the tendency was there, however, as the front end shook ominously on several occasions. The only feature of any real interest was the suspension. This confirmed our previous impressions as to it being very good, both in the back and front seats.

We believe the excellent suspension to be mainly due to :- contd :- | ||
