They came out of 2 diffrent airplanes and I wish I could tell you. We got one with the plane and the other we bought from Peter at Skywagon City. Just as the one gent posted about the 2 diffrent styles. You want to go with the first generation like my cousin did because the second generation are 15 to 20 pounds heavier. Our grandfather had the second generation in his '55 180 but he got a real good deal on them at Sun and Fun $30 each! That wa in the early '90's.
Good luck and keep it light.
