I think the model is 'St. George(s)'
Ive seen them listed both ways,,,St. George,, and St. Georges
Made in Skeet,,Trap,,probably other configurations. Sporting Clays maybe. Maybe just a hunting model as it has 2 sets of bbls.
Not much bbl changing going on in the clay target games,,just plenty of choke tube switcheroo.
Some St George(s) have the side plates as this one does,,some do not. So again probably another variant designation in there.
Case colored finish on some,,'Coin' finish on others.
The side plates are called 'false sideplates' as they mimic the looks of a sidelock action. It being actually a boxlock action with the false sideplates fitted. The reason is to enhance the looks and to give greater area for engraving.
Can't help w/a price range,,not up on the newer stuff.
Not sure if it came from Antonio or Angelo,,but should say somehere on the gun.
