The Sauer an Sohn M35 double - the action strongly resembles my Simson Suhl .405 WCF.
I have wanted a 45-90 double for a while, but this one looks expensive.
Especially since I can have plain rifle made for $4k or less.

CORRECTION - When I properly converted SEK to US$$, the rifle may not be overpriced if it is functionally sound.
How can I get an English translation of the description of the rifle and ask questions about it?
