| Mr Wormald. 11.7.12. Re Valve Springs. TBB11/L11712. With reference to Mr Royce's note of July 2nd concerning the above matter, I have passed on to Mr Nadin a standard valve spring made by Messrs Salter (which has run on the test rig for the equivalent of 10,000 miles without failure) in order that he may obtain the required analysis. When Mr Nadin has obtained suitable material or suitable raw springs (whichever he is able to do) will you kindly proceed as directed in the above mentioned note from Mr Royce. T.B.Barrington. | ||
