Ya Know;
There is a good story there. I seem to remember more than those three in the bigger scheme of things. There was ADAMs, Renwal, Marx, Lindberg et al. Now that said, it's true the ones I mention were Toy manufacturers of some history beforehand. Oh, and let's not forget Strombecker, who didn't seem to be able to figure out where to stay.
I remember Comet and a few others Guillows comes to mind. For me, who, even as a kid was slower than most in building.The Comet models and Guillows models that flew Flew beautifully. Because I built patiently. My solid wood forays were successful because we got graded on them in wood-shop in school!
I saw model building then as a get-away from the younger siblngs. And, a way to learn something I didn't know. The Library was my friend for model Boat plans too!
