My first plastic WW1 kit was the Lindberg Curtiss Jenny, sometime around when I was 8-10 years old back in the early 90's. Second plastic one was an Eduard Sopwith Triplane. Also very close to those in time was a Sterling Sopwith Camel stick-and-tissue free-flight model, which I remember being a great flier. I still have all 3, though the Camel's flying days have ended. My very first model ever ever was a 1:25 AMT 1927 Ford model T when I was 6 years old, and since it did not survive the rigors of childhood I have since searched out another to build and have it waiting in the car stash. Airplanes come first though!
