I was looking thru my library tonight and open a book I have not read in awhile Aviation Engines by Lieut Victor W. Page copyright 1917 and stumble upon these pages. Take a look at just how advanced Sunbeam engines were in 1917, 500hp and overhead cam with three valves per cylinder, just amazing. I thought some of you might enjoy a look at these engines designed by Louis Coatalen. Engine pictured is eighteen cylinder 475hp OHC six magnetos, two on each bank feeding two spark plugs per cylinder. The quality of the castings are beautiful and way ahead of its time. Almost looks WWII vintage not WWI.
