I had that exact same kit as a kid! I remember the weather wheel and how it taught me about nor'easters, and even remember permanently marking the barometer as Hurricane David (1979) passed overhead since it would probably be the lowest pressure I would ever see.
The wind speed didn't read directly on the gauge. You had to watch the dial move over a certain period of time and the difference on the dial was the wind speed.
I'm tempted to bid on it, but I honestly don't have the wall space for it.....
