Good morning stearman70, Indeed what you have pictured is a 'tractor' engine installation and it does not need a pusher prop or reversed engine rotation and the airplane is definitely not a Northstar.

Instead I strongly believe what you have is one of the many dozens of designs from Bill Evens and one of the names he used was Scimatar (spelling). At least that was the name of the version I built and flew back in the eighties. All his many designs were very close in formula. Most were front front engine tractors but also I believe a few did include a pylon mounted tractor. All were tricycle geared but included many variations of a relatively straight wing leading edge taper, trailing edge taper or double tapered. Mine was mild double edge tapered and was a front engine tractor. I also believe most all his designs used the same formula of roughly 10 degrees up reflex of the two control surfaces along the trailing edge at neutral coupled with a CG at around 15% mac which is further forward than conventional airplanes at around 25 or more percent.

My little Scimatar , I believe with and old K&B forty was a delight to fly and great fun. As far plans I cannot help but think (Bill Evens Scimatar) will be a good place to start your search.
