I think it's restored. Everything is too bright a polish under the finishes. The stock has what appears to be a crack at the rear of the left lockplate inlet. Tough to get that on a gun with zero breech face wear.

Small chips to the stock fingers on the bottom where they meet the frame. Again not very likely on an unfired shotgun.

Lever is in the center.

Colors & polish look like Dougs from very late 80's, early 90's.
Checkering is pointed, IIRC it should have been flat topped.
Look at the small screw on the bottom just ahead of the trigger guard bow.
That's the lever spindle screw. The spindle has to be pushed over into position to be able to get the screw in. A popular method was/is to use a center punch in there to lever it into position leaving a damaged edge to that edge of the hole.
It won't be much sometimes,,other times it will be very apparent.

Factory didn't do it that way,,
Nor did the factory cut wood out of the thin web inside and push the spindle over from the side with a clamp like some 'gunsmiths' do. But you'd have to take the lock plate off to see any evidence of it.

One lock plate has it's forward screw misalligned,,not qualified.
They are fitted and then flat polished in place. No reason they shouldn't go back into place.

The bbl lug showing thru the frame on the bottom looks like it missed the polishers attention when doing up the rest of the tubes.
It's rounded, uneven and lacks the crisp polish of the frame, iron and other parts.

All that perfect wood 'original' finish and then a non original (IMHO) pad fitted w/ no disruption to that finish. Very difficult to do.

Just some observations from the photos. Pics don't always show the real story though w/ shadows, focus, etc playing tricks sometimes.

All that said,,it certainly is a shotgun I wouldn't be shy about taking out to the field.
