I have a mint one too Tom, something about these little guns that appeal to me, great blacking etc, the trigger can be fettled and the power on the one I have is 11ftlb in .22 which is rather good for one of these, I have fitted a rear guide which helps sweet shooting

Unfortunately mine is the beech version with wood that wouldnt look out of place on a cheap chinese cricket bat Unlike your Walnut version
