Oh, I do have one kit that is my one-kit collection. Just after WW2 I discovered a kit, a balsa wood kit, of a midget race car. Since my dad was a midget driver, I was really interested in that kind of racing, and built a number of those kits- they were by far the best kits of race cars. A few years ago, after putting out my desires in a number of forums, a fellow replied and sold me one of those old kits. Now, these kits consisted of various size blocks of balsa wood, wheels, some fittings, and plans. I was able to buy and saw up balsa wood to match the kit ones, make molds of the wheels and cast them in resin, and reproduce the fittings from raw stock, so I still have my kit, and built the model too! But one collector kit does not make me a collector.
