I've dealt with them a bit. The Partridge (AKA Bobwhite) was their mid-grade with a straight grip English stock. Action is a box lock with non-interceptor sears. Nickel finished with some simple laser engraving. No third fastener. Made by Huglu in Turkey. They are well fit, and tight. In fact, they are usually hard to work until you open/close them a couple hundred times. Triggers are typically stiff, though. My experience with them is lightening the triggers.
Solid shotguns. Balance well, and don't have any weak points from what I have seen other than the triggers. A good copy of a typical English grouse gun, but made with better metal. Meaning, steel alloy for the receiver and fully heat treated, not case hardened.
They went for $800 or so new. I'd say 600 would be fair for a used one in good shape. 700 for as new in box, or similar. And that is what they are worth. Plain wood, no engraving, and mono-block barrels.
That said, you would be hard pressed to match it for the money.
I have the cz bonwhite in 28. Very similar to your partridge. Solid lock up, carries and points well. My only complaint is that the triggers seem to be very heavy, even for a shotgun.
