Here is one on eBay if you have deep pockets .
Ha, I am hoping to find someone who now wants to builds 1/12th scale cars and just wants to move an unloved kit on.
You may want try to get the kit with the Hermann Goering figure as it is a D.VIIF. The only disadvantage is the markings, and I believe Lifelike and some other companies make decals for it.
The challenge is to find the Fokker DR VII kit of anything in the Wingnut kits.
