| X523 BY.{R.W. Bailey - Chief Engineer} FROM R.{Sir Henry Royce} (At Le CanadelHenry Royce's French residence.) R2/M14.4.31. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} C. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} HS.{Lord Ernest Hives - Chair} MAYBACH AND OTHER PATENT ROYALTIES. X.523. X.2200. I quite agree with BYS/G30.3.31.. re. Maybach jaws. so far we have not had much success with these. Anyway we should not feel like paying either £1500. or £4. 12. 6. per chassis. We would rather put the money in extra work in the designs. According to what Mr Ricardo tells me his firm does not demand in royalty such a relatively high price - i.e. for his combustion chamber on a 4 litre engine they charge £1. = 5/- per litre. We can use the same as Bentley is adopting if we wish. R.{Sir Henry Royce} | ||
