I'd say it's the Hanger 9 ARF 100" Cub. Just compared your photos with the one in my shop and it looks identical around the cabin area. Seems to be some decals missing, though. Mine is one of the original fabric covered versions but later they were film covered. If it is a H9 you can get the cowl and windshield from Horizon Hobbies.
