I have a nice example from 1995 which came with paperwork including an “Air Weapons Final Inspection Certificate” stamped for accuracy compliance at 25yds ! The pistol is quite top heavy which puts some owners off, but I get along with it fine now that I have become accustomed to it. Mine doesn’t really live up to the “Magnum” tag but quite powerful enough for most purposes. The polystyrene packing tray within the box has what looks like it has extra provision for a longer cylinder and I believe there were plans to include this which never made it into production.
