Yes, OQ does take some learning. It is not a strict quality of the gun. Rather, it is how the market assigns value to the quality of the gun. The market does not assign the same value to a best work SLE and a best work BLE and I do mean a best work gun for the BLE - every bit the quality of the SLE. Note that the "C" grade SLE at OQ4 out ranks the best BLE at OQ5. Hammer guns are valued like boxlocks by the market except HG's are expected to be non-ejector.
My bottom value of $800 (based on the photos) with a 10% ding for 10 bore comes out at $720. I think we are on the same page here. Depending on the bores an d stock, $800 would in no way be unfair.
