I agree with the above advice. I think that the cowl you have there does go with the fuselage as the paints seems to match up from what I can see at that angle. But those tail feathers definitely do not go with that fuselage. As others have said, if you were sold a plane missing "a few parts" then you paid too much. There is actually more of the plane missing than you have in your hand. No wings, tail components, no canopy, no landing gear, no wing tubes, and a bunch of other missing parts. Follow Stickbuilder's advice and set this aside and get an easier project to complete.<div>
