STAMPS: CHASSIS Recd 14 JUN 1932 INITIALS TABLE: INITIAL | DATE | REMARKS SG.{Arthur F. Sidgreaves - MD} | 14.6.32 | Agreed S.G. R.{Sir Henry Royce} | 1.6.32. | The patch on 16-G4. looks rather commonplace and I should make sure all the instruments are reliable. WOR.{Arthur Wormald - General Works Manager} | 25.5.32. | Agreed Wor.{Arthur Wormald - General Works Manager} C. | 9.5.32. | Agreed C. RG.{Mr Rowledge} | 6.6.32. | Agreed Rg.{Mr Rowledge} DA.{Bernard Day - Chassis Design} | 13.4.32. | Have not seen instruments. From drawings method of securing instrument in patch does not seem proof against vibration. Illumination looks as if it would be inadequate. DA{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} | 9.5.32. | Agreed BY.{R.W. Bailey - Chief Engineer} EP.{G. Eric Platford - Chief Quality Engineer} | 9.5.32. | Agreed EP.{G. Eric Platford - Chief Quality Engineer} Instruments look cheap and 10,000 miles test should be carried out and reported on. E.{Mr Elliott - Chief Engineer} | 18.5.32. | Agreed AE. Also suggest better lighting to see lower instruments. EP.{G. Eric Platford - Chief Quality Engineer} PN.{Mr Northey} | 9.5.32. | Agreed PN.{Mr Northey} HS.{Lord Ernest Hives - Chair} | | Agreed Hs.{Lord Ernest Hives - Chair} | ||
