Hi! Yes, I have these. I plan a mini review serie about these kits. There were 20 participants (21 if You name the disqualified "Irish Swoop" Bellanca 28). I collected many of them through the years in my stash and more to come. I have the Boeing, the three comets (two Airfixes and an excellent SBS), Special Hobby DC-2, Contrail Pander S4 (vacform), Gee Bee QED (strachbuilt), Miles Hawk H2 Mayor (strachbuilt - in progress), Heller DH.89 Dragon Rapide (converted), Kora Desoutter II, Planet Models Monocoupe 90 (to convert into Lambert Monocoupe 110), RS Models Airspeed Envoy to convert into Airspeed Viceroy, and another one of this kit to convert into a single engined Airspeed Courier, MPM Lockheed Vega (the decals are wrong 🙁 ), Doujin Bellanca 28.3 (it is so bad actually that I will make a strachbuilt one instead), Pegasus Fairey Fox. There are some plane that missing: a British Klemm, a DH Puss Moth, and a Miles Sparrowhawk,
