Just out of curiosity, wondering what everyone thinks of this gun:

Apparently originally a 12 bore, enlarged to 10 bore but with ample wall thickness throughout, chamber sleeved by Merrington, Briley chokes installed along with a modern recoil pad.

If you would consider buying it, what would you pay for it? Not planning on purchasing, just curious particularly given that I have a similarly overbored hammer gun (which I posted about previously) and am deciding what to do with it.
