If I am in the market for British guns, and I often am, I think I would rather have the traditional 2 1/2" gun. I know I would rather have it than one that has had its chambers lengthened. Thinking further, I guess that I have no 2 3/4" guns at all, so it would make zero difference to me if I were to buy them from your wife at some much later date. Prolly won't be around to buy them but you get the idea....I like 2 1/2" guns and all the Brit gun enthusiasts I know do as well.
