What is the age and value of a 12 gauge Charles Daly Model 106399 side by side double barrel shotgun made in Prussia?

That's a much higher number that I;ve seen on a German Daly but their numbers are hard to track as they started over in 1892 I believe. I believe your gun to be towards the last. Its all the other numbers on your fine gun that give a truer answer.

All proof marks should be added here as well as any writting on the gun. I'm thinking this gun is out of the number range for a Lindner gun but nothing is for sure in the gun world.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
