This is a tin lithograph windup helicopter made in Korea. 1950’s Vintage Antique. The windup mechanism works. The blades are plastic. The entire helicopter is 8 1/2″ long INCLUDING the rear blades. The helicopter is almost 4″ tall. The width of the body is 2 1/2″ when you measure across the wheel. Excellent vintage shape.The colors are still nice and bright. The blades , engine and wheels are plastic. The two front wheels cause the helicopter’s wings or blades to rotate. The tiny 3rd wheel is simply there for looks and stability.
