Is it a non-ejector gun? There is no photo of the extractor and I don't see a pivot pin on the forearm. Would "heavy use, but no abuse" accurately describe its Current Condition? Or, does it need some work now? Does "second grade BLNE" sound right for the OQ? This based on the engraving coverage and stated nice wood.

Assuming it is BV3-OQ7-CC4 = $1,233 (12 bore). 16 bore guns are running about twice the price of 12's. So, figure $2,500,unless I have overestimated OQ or CC.
