I stumbled across this subject some months ago when looking to see which types of aircraft had participated in the early post war American races. Google revealed the cover image of Don McVicar's book "Mosquito racer" and I was able to find a copy on abebooks for a few quid. The kit was picked up at Teflord where Antics were selling them for a tenner a pop.
Anyway, tidied the garage today so that the bench is once again accessible.
The kit and the reference book.
Unfortunately the only colour image in the book is that cover art and other searches have revealed just one profile drawing and a skin on a flightsim forum. The book is specific about the colours though, "My choice of a paint job was was a delicious light yellow shade called Diana Cream, offset by a trim strip of sparkling Stinson Green".
The image below is a rough draft for the decal artwork and the initial work was very kindly done by my good friend Rich Hutton in Glasgow, who shares my interest in civilian versions of warbirds and was a graphic designer in a former life. A couple of days after a late night phone conversation a surprise email arrived with marking for one side and the wings. The colour will need tweaking and the original re-sizing to fit the kit properly, but it's a very useful start.
