They are getting tougher to find! I have been lucky to come across a couple. I picked up a beautiful all matching 1938 J.P. Sauer at the local gun shop.. (It was duffel cut.. and was priced as a 'project" gun..

I will not disclose what I paid, because I feel it would make some faint

) Regrettably I did end up selling it. But it went to a great collector so I'm happy.
This is a 1944 BYF I grabed on Gunsamerica. I contacted the seller within about 20 minutes of it being posted. And luckily I was the first because he had 5 calls shortly after mine. All matching except the Stock (and the lower screw is numbered but not matched, and from what I researched it should not be numbered anyway). I also added a nice original sling. Lastly, as you may know.. be VERY carefull.. with all the Russian captures that hit the market, tons of fakes are poping up.
