| STANDARDISATION of CHASSIS PARTS. COMPLETED 10.7.23 Description of Parts: IMPROVED SPRING DRIVE. Origin: Improved design. Experimental Test Report: The chief advantage in the improved design is that it does not require such accurate work. There can be no slack between the friction damping and the spring drive. Road Test Report: Fitted to 7-G-11. * 3-G-11 Ran 11,450 miles. Recommend we adopt this at once.
