OK, OK, not a "Bore Rifle" or Paradox but a very economical entry into the world of 8bore cartridge guns!

R. Wallis 26 Trothy Rd. Southwark Park Rd. London on the full length rib.

My desire is to use this gun as a shot & ball gun as the barrel is now 29.5" which almost certainly was once longer as most of these 8bore guns were well over 30"
If it is truly cut back and cylinder bore, it should fit the bill nicely.
I especially like the shape of the trigger guard and lever.

Overall, a nicely proportioned and high quality gun that is a good evolutionary step up from my Rodda muzzle loader.
