This set consists of three accurate, late style control columns as fitted to cannonarmed Spitfires of all marks. It has the rectangular three position trigger switch as fitted to all Spitfires and Seafires from the Mk Vb on, including the PR variants. The column is molded complete with very fine pneumatic hoses for the gun firing mechanism. The modeler simply needs to paint it and install it. A very nice upgrade for your 1/72 Spitfire models. Designed to be used in all kits.Designed by Mike O'Hare
