My cOde rates it for sure LOF...lOOse on face as stated. A price would be hard to determine just from pictures.

Hope the bores aren't pitted also. If they are that could rate it LOF-PB (PB stands for pitted bores)

If the pits are bad enough...it could push it into another category LOF-PB=PWF (P stands for 'Possible', 'WF' stands for Wall Flower).
To put it bluntly...Loose on face with badly pitted bores could maker it a wall flOwer.
You didn't mentioned cracks inb the stock. If any are present that could throw it into LOF-PB=PUWF ('PUWF' is possible ugly wall flOwer)

All kidding aside....If it was my gun and I couldn't evaluate the condition myself I'd have the gun evaluated by a competent gunsmith.
If it's not too bad with a little work it could turn into a $2,000 gun....problem is it might cost more than $2000 to get it there.
