| X2cp April 26th. 1912. Re broken valve spring on 1600 Mr DeLooze. 26.4.12. TEE1/L26412. This appears to be a similar failure to a number which we have had recently. We are making extensive experiments with various types of springs, and also in connection with different material and heat treatment. These experiments are being pressed forward with a view to overcoming this difficulty. In the meantime I do not think we can do more than replace any breakages of springs from the latest delivery from the manufacturers. File Brekuyes X654 | ||
