I did speak directly to Bill last evening, and ventured much the same opinion as Benson. It is always difficult (and even dangerous) to venture opinions on value without having the object in-hand for close inspection. Based solely on the photos I have seen, taken at a distance, the model is missing both seats as well as two thwarts. There also appears to be a slight break in the keel and the paint seems to be flaking and somewhat faded. I was told there is no structural damage or rot, but there is some paint missing. I'd really like to see close-up photos before absolutely committing.
However, based on recent market trends, it would not surprise me if it brought $6,000 to $8,000 at auction. I would expect to see a pre-sale estimate range of $4,000 and up. If it were in more complete shape and cleaned up a bit, I think it could bring $8,000 to $10,000, and possibly even higher if lightly restored to near its original condition. But that takes some work and even further investment, as well as the gamble that it will pay off in the end.
Others may well feel differently about it. That's what makes a market.
