I think you would get more serious interest in the sale of this Test Eagle on Jan Still's site. A thread similar to this, with a corresponding thread in the For Sale sub-forum there. My reasoning is that Still's is a serious collectors place, and is more geared to the serious collector whilst this site is more for the casual collector. IMO you can get more $$$ for it on Still's site.
Thor's work is excellent, in my mind his recreations are as close to original as is possible.
Gunbroker.com is a great place for run-of-the-mill handguns but for big-money items Simpsons or Legacy (with attendant consignment fees) is a better bet. Again, they attract the high-end collectors.
Just my $.02...
