I like the lines and looks overall, but a lot of the close-up details leave the rifle short IMO.
The wood/metal fit around the action isn't what I'd expect, kinda sloppy especially if someone like O'Connor was excepting of it.

The 4 holes in the front ring aren't comforting but may well be better looking than that engraving. The whole thing has been heavy handed buffed and blued anyway,, rounding details and edges. No telling what hides under the rear sight bridge as far as holes.

"...the bore looks quite good with decent rifling as well as quite shiny..." ,,,just say the bore is in fair condition only and be done with it.

The floor plate & TG engraving kind of looks like the same pattern as the top ring but don't. None should have never been hammered on to the gun.
The bbl address looks amateurish, maybe that's the way it was done by WmS. I don't have anything to compare it to and don't have any real knowledge to say one way or another if it's 'real'.

Grip cap engraving is way different than the rest but maybe the cap came engraved as a feature.
The butt pad, sad to see the 'German Trap Buttplate' gone. But that note,,?? I certainly wouldn't pay extra for that Bic-penned documentation!

I'd certainly stop and look at that rifle had I seen it on a table at a show or on the rack in a shop. Maybe in person it would lull me in to taking her home with me for the sold price. But just from what I can see, I'd have to do a bit of back and forth for a better price.

Just some observations over AM coffee.
