Mate, I'm trying to get a look at it, but the Thadster appears to have photographed it in the depths of an abandoned mineshaft during a solar eclipse! Dunno why he would do that unless hiding something. If you want to sell a gun on the internet, a good photo is crucial. That one's crap!! Can't help but suspect the gun may be too!

Still, all shots well inside the 9-ring at 60 yards is certainly a useable .470! ...even if it needs a bit of TLC!

FWIW, my Manton .470 was made by John Wilkes. Those in the know will appreciate what this means: its a ripper!
