Back in the 1970s, the Evening Capitol newspaper, for which I delivered newspapers and my father, Art, was the classified ad department manager, had a contest where if you signed up a certain number of new customers, you got to chose from a list of prizes. The one I coveted was a set of Cox WWI airplanes. I know it included a Fokker triplane and a Sopwith biplane, but for some reason I think it had a third model; I just don't recall which - maybe a Fokker Dr VII biplane. If you can find ant of those models now, they are selling for a couple hundred dollars each on eBay. I recently happened for snatch one for under $100, though, because it did not come with the original box and accessories. It appears to have never been flown. Now I just nee the Sopwith Camel, along with my Fokker DR.1 Triplane to complete the set.
"The Fokker D.VII was a German World War I fighter aircraft designed by Reinhold Platz of the Fokker-Flugzeugwerke. Germany produced around 1,700 D.VII aircraft in the summer and autumn of 1918. In service, the D.VII quickly proved itself to be a formidable aircraft." - Wikipedia
