I think I can see enough of the door to say it's not a Kitfox 1. (Kitfox 1 is only 36" wide as well at top of seat) (2, 3, and 4 are 39 1/2" wide there) So with the ribs acting as hangars for the flaperons, it must be a 2 or 3. If it's a Kitfox 2, the distance on the front lift strut, bolt to bolt will be about 98". The Kitfox 3 will measure something like 10" longer. I don't have that dimension handy, but it's much longer than the Kitfox 2. Hope this helps. JImChuk
PS, looking at the pics again, and the angel of the lift struts, I would say a model 3, but the measurement I gave should tell the tale.
