RE. REGENT PETROL.

Roy{Sir Henry Royce}/GEA3/EB25.10.33.

Further to our memo Mx{John H Maddocks - Chief Proving Officer}19/T27.11.33 - we have now had an opportunity of making a more complete test with this petrol. There is, however, nothing to add to our previous report which is confirmed in every particular by the latest report.

The chief fault lies in the inconsistency of the carburation which is very "fluky".

The carburetter control is in use the whole of the time to obtain the best results.
