The value of any gun depends on a lot of factors like age, condition, size, and finding the right buyer. By double barrel I assume you mean SxS instead of O/U. I'm not familiar with the SxS value but I just saw a 12 Ga in pretty good condition advertised for $400.
While I'm not a double trigger guy, that seems like a fair price. But, you need to make sure the barrels are regulated to shoot properly. I have an O/U 28 Ga Richland Model 828 that I love .
Although it isn't in very good condition, I'd have trouble finding one that is as light for 2 times what it is probably worth to most people. I have friends who have looked for a Richland Model 828 for years without finding one. Another friend collects all Gauges of Richland O/U shotguns that were imported from Spain or Italy into America in the 60.
I paid about $800 for mine several years ago but that was probably above the top dollar for the condition it was in and then I spent about $400 more opening the rifle chokes and refinishing the stock and making new firing pins. I've heard they are only worth about $500 in the gun value books but personally, I think that price is too low for the 28Ga O/U. There are also new guns being sold under the Richland brand but, they are not at all like the Richland guns imported in the 1960's.
If you have a Richland O/U for sale, please let me know.
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.
