James:
Your comments and guessing value are just great for me.
I am "south of the border" and here almost nobody knows about fine and old shotguns.
Your shotgun is really in excelent condition; the one I talk about, for sure, once was as beautifull as yours, but previous owners do not take care of her.
I will offer the $400 USD you advise me and see what happens. I can do some reworking to the wood and obtain a serviceable shotgun.
If the shotgun "change hands" I promess I will show some photos on the forum.
Thank you for the helping.
Best,
