Iv'e been to the Dells Museum several times and talked with the owner about 3 years ago. He is an older gentleman who has been operating the museum as a tourist attraction for years. He had cars for sale pretty regularly at the museum and sold some of his private collection off and on.
The cars from the fire are being held in another building awaiting their fate. The insurance company was balking at the value determinations the last I heard so it may be years before it is resolved. Cars probably will be sold off at some point but they are in limbo for now. The fire was very hard for him as he lost some very rare cars and basically his life's work.
In addition to the 70 Pepper Green Judge there was a 64 Red/White GTO vert and a 68 Firebird 400/auto that were burned also. I know he had about 6 first gen Camaros get burned up. 80 cars in all. Very sad deal.
