| C.R. 235A (100M) (FP {F. Potts} 351. 2.1.13) G 4088 AW/SM28/014213. Re X.74 - VALVE SPRING TEST. Mr. Nadin. 14/2/13. You will notice on Mr. Royce's memo R1/B11213, a copy of which you have that he suggests that the testing rig for these valve springs be run at a quicker and slower speed. This we understand will necessitate a new pulley or pullies being designed for the existing rig. Will you kindly instruct Mr. Moon in this matter. Also, in accordance with Mr. Royce's request, will you endeavour to obtain several valve springs similar to those used by the following firms:- DeDion. Metallurgique. Brazier. Vauxhall. Sunbeam. Napier. p. A. {Mr Adams} Wormald. | ||
