Evidently the owner of this collection has done this before, sold everything off and started over. I'm not saying that's what's going on here, because I don't know. Obviously, the owner is very well known, has a good eye, has the funds, etc.
So true, if you think your gonna offer up $125 bucks for a $5000 rifle, you'll no doubt be disappointed... On the other hand, most antique prices are currently on the low side.
