Hi Frank,
You never know what you might see. Denny and I, as well as my eldest son, Archie are in the process of organizing all our old plans and we are seriously considering copying them all in CAD. We might even have some kits laser cut. That will really depend on if we can find a good source for the cutting.
While I was taking a break between drawings, I sketched a new design that has a removable two-piece wing. Each panel is 40".
