Here’s a nice looking double that should make a nice bird gun. It’s listed at Gunbroker.com and auction ends on 2/14/2014 @ 11:45:19 AM ET.
I think this is a pre-WW2 Sauer, and it appears to be in decent, original condition. The seller has done such a poor job of describing it that I doubt it will bring anywhere near its real value. But if you’re feeling lucky, it may be worth rolling the dice on it.
