Chuck, the Petton gear doors were done by a fellow named Bob Petton in the 60s, for his 14-13. He set speed records with his plane and claimed to have gained 12mph from the gear doors alone. He sold kits with instructions and lots of people bought them, but I dont think very many people ever got them approved. Petton did his on a one time STC and I have seen a few planes with them on that just used his STC number. I doubt that you could get away with that now. The fairings and doors were really nice ,but the hardware was flimsy. The reason I said I might have the doors from your plane is the set that I bought years ago came from a 14-19 with an N number that was yours or very similar. Im not sure at this point. The doors were removed from the 14-19 since they slowed the plane down. I later saw a photo of the plane flying overhead, and the doors were hanging open an inch or so, which must have created lots of drag. As I said, the hardware was flimsy. The most beautiful Bellanca I have ever seen was the late Bob Hedlunds Cruisair. It was just out of restoration and had the geardoors and a varnished wood prop. It looked like a time warp had happened and we had just arrived at a thirties air race rather than a modern fly in. If I had better computer skills I would post pictures , but that is beyond me. The club has all of the drawings and instructions, so it is available if you are still curious. Good Luck with your restoration._____Grant.
