Are there any retailers in the north west, or anywhere else for that matter, who specialise in match airguns and have a decent selection of second hand products?

I am aware of City Air Weapons in Solihull, and Checkmate Guns in Chorley, but is there anywhere else?

I'm thinking of pcps mainly but also interested some of the older spring and single stroke pneumatic pistols of the seventies and eighties.

The reason I ask is because I haven't found web searches to be much use.
