Lamarque B.Sc, A.F.R.Ae.S. which was published in the I.A.E.Journal in June , 1943, a digest of which was prepared by Phil Irving and published in Motor Cycling on July 22,1943 under his Nom De Plume of Slide Rule.
The relevant passage is - " With regard to surface finish a coat of smooth black enamel is an advantage, provided that it is very thinly applied, whilst a coating of oil makes little difference either way to the heat dissipation."
Phil went on to include a black coating in his design of the Vincent Black Shadow and Black Lightening motorcycle engines , and from all reports the result was more than satisfactory.
