Home Forums Hunting & Shooting Combination Guns and Drillings Help with rough value

An elderly lady that is a friend's neighbor has a Sauer drilling that her husband took from the factory at the end of WWII. I dont think it has been fired. If it has, it was very little. It's a double barrel 16 gauge with an 8mm rifle barrel. The lady wants to sell it and asked my friend to try and get a realistic value on this nice
Firearm. He contacted me because he knows I'm a gun guy. I have not a clue how much it's worth, but I don't want to see her get taken. Any ideas would be appreciated. These are the only pics he sent me.
