Found the item below (if pics work) in the skip at work today and i must admit it's got me a bit flumoxed, it would appear to be in "used" but original condition although the sights may be an aftermarket add on but they do fit very well and enhance its' looks. The calibre at a guess is 2.2 (sic) and the gun itself is of a variable pump up design.
Can i retire early on this one?
