Roy Browns's Engine cowling was RED. i saw a fully reconditioned Sopwith Camel in his paint scheme. Three strips aft of the cockpit, one twelve inch back, 6 inch wide. then twelve inch further down another 6 inch wide strip, 6 inch down and the last strip 6 inch wide. Got photo of this Camel at Biggin Hill airfair England in 2000. it belongs to a company at Brooklands aerodrome. not sure if this Camel is correct but it might help you if you need any more information
