RE: Ed Kazmirski's Taurus
One thing you'll notice, the Orion in the museum is NOT the same Orion Ed won the first "worlds" with because it has a "trike" gear. My guess is that the "trike" gear plane was later when the need for accurate taxiing became more obvious.
There is no way to know for sure, but this orion in the museum could very well be the SAME Orion Ed had with him at the White Sox stadium in the picture below.
