The problem with any or all of this supposed, "historic significance" that people say is, or else might be attached to these guns, is none of it can be traced. Traceability and the documentation that goes with it, is crucial for ANY firearm that has increased value through the history that is allegedly attached to it.
The only knowledge you have with any of these things, is who made them, and possibly when they were made. And even that information is doubtful because most all of these guns have been rebuilt. Many of them several times. And in the process have had their parts mixed, matched, and replaced by God know who. And God know where or when.
You have what amounts to 10,000 G.I. issued .45 pistols that have all gone through the U.S. arsenal system over a period of decades.... And the mechanical ringer at the same time. The purchaser has no knowledge of where they've been, who carried them, or which, if any "war" they were ever involved in. Or even if they'll work, or be safe to shoot when they get them. And you have no choice in the selection process. You're going to get whatever POS they happen to grab, and decide to ship to you. Can you think of ANY product you have ever owned in your life, that you paid $1K or better for, that you would have EVER agreed to purchase in this manner?
So in the end, (assuming you even get one after you have jumped through all of their ridiculous hoops), you will have paid close to, if not over $1K for a used up, shot out, parts blended rattletrap 1911, that you have zero knowledge of where it's been for all it's existence. It's much like adopting a homeless mutt at the pound. At least there you can choose which one you want, and it will cost you a lot less, and be in perfect health when you get it.
