After building the Fiddler's Green S-38 and S-39, I hankered mightily for the S-40. An even more challenging model to design, I quickly found. There are two paper models that I know of, the bobcardsmodels version, and very recently, the beautiful S-40 that Aaron Murphy designed. I find Aaron's models captures the graceful curves of the hull rather better than the other. Here it is now at ecardmodels.com:

And then, there is the S-42. For that, the 1:100 Scissorsandplanes model is a good one. I recently experimented with building it at 1:50 It enlarged very well. Then there is the S-43 Baby Clipper, and the giant S-44 which await the intrepid designer. Will post pictures when I have a bit more spare time.
