Thanks for the photos. C&H is factually a Brand Value three (BV3) maker. This gun is without doubt a second grade boxlock ejector which is Original Quality grade six (OQ6). The current condition is hard to nail down from the photos. The chewed-up, out-of-clock screws give me the "willies" and could indicate improper disassembly/assembly (the right extractor guide looks damaged); there could be some damaged bits and pieces in there. A guess at Current Condition level CC7 (heavy use with some abuse).

BV3 - OQ6 - CC7 = $687

I'd opine that this is not your best choice for entering the Brit gun market.
