The point I was trying to make in my previous post was that many 'Best' guns may have started life elsewhere before being proofed and finished in London.Certainly actions & barrels were made in and around Birmingham pre & post WW2.
Undoubtedly it is a matter of pride to own a Purdey,I used to own a Boss O/U but as many who have owned one will testify owning and shooting one is a very different set of circumstances.It was not very nice to shoot, very 'lively' in the hand and second shot required 'application'.
