Does anyone remember building these screwdriver kits? No glue just screw together, poseable flaps and absolutely no bottom to the top and bottom wing. I liked these kits as a kid because they were easy to build and very large. Notice the price for the Fokker, a whopping &3.50 I believe in 1968 dollars, today it sells for $200 - $700. I cannot remember how much the B25 originally went for. But I see the B25 can run from$200-$500. I think I also had the SE-5. I also think they were supposed to be flying kits.
