That is the first Premier I have seen with the oak leaf engraving commonly seen on the Excellentia models.

Cases generally don't add any value if not original to the gun. Even then, if the accessories are not included the case still adds minimal value.

I haven't seen many 12ga Premiers of this era and style exceed $10,000 in price, with most far below that.

So IMO, that gun is significantly overpriced.
