The ends of the muzzles look correct. The proper keels are in place and the rib ends the same as my 32" 12ga 1900 with the anti-glare pattern all the way to the end. I also checked the depth of the chokes on my 12 GA and they start the same depth in the bore and have the same continuous taper to the end.
You can see the almost buffed away XKD in this shot and the faint Damascus pattern:
I forgot to mention the ejector hammers do not stay cocked when I remove the forend. I have to re-cock them by hand to re-assemble the gun.
