This is a unique design, aimed at bein' a futuristic/sci-fi type spaceliner.  It basically came about by combinin' 2 BT-60 sized V-2 boat tails, and a BT-50 Honest John cone.  T' win' shape and name "Cygnus" came from t' resultin' long "neck" with bulbous head, which reminded me a swan.  T' model has been built and flown, ya bilge rat, but isn't yet painted.
