| COPY. NOTES ON CARS. X200 CHASSIS WEIGHT. This continues to rise:- Cwt. Qrs. Lbs. Before 1550 25. 3. 0. Since 1550 26. 0. 0. Series 1700 26. 2. 19. do. 1700 large flywheel 27. 1. 8. do. 1800 & 1900 27. 2. 10. The above approximate weights are what we calculate in London and are for chassis fitted with standard wood wheels, and include, water, oil, petrol, and tyres. The rise in chassis weight means that more cars are now over the maximum limit weight of 50 Cwt. (5600 lbs.) LARGE ROAD WHEELS. We find these make a marked difference in the running of the finished cars. Going over the same ground as we do with several hills, the cars with standard 895 m/m wheels invariably run better than those cars with 935 m/m wheels. SIDE BRAKE LEVER. I continue to receive complaints that the lever is too far forward in the "off" position with "B" and "C" columns. In a few cases with "C" column, both speed and brake levers have been set in "D" position, which seems to be an advantage, though perhaps a little too far back. | ||
