It's a nice gun I don't think the sellers claim that "The gun itself is equal in quality to a Purdey or other top London maker" is true. I'd say it was a fair price if you were looking for a smaller guage and like a box full of trinkets that you'll never use.
I do think it's allot nicer gun than the 28 guage Thomas Bland listed on there.
