I have serial number 1174 "T", an A. J. Aubrey which is a twist not a Damascus barreled gun. The engraving looks very much the same. It also lacks your 90+% condition, being more near the opposite end of condition and care. I bought it as a project gun for a very reasonable amount. When received I found it had a ring bulge in the right barrel. Four of five years later I realized the ring bulge was more likely the result of some morons attempt to raise a dent using a steel plug at a angle wedged in the barrel or a hydraulic dent remover. Perhaps someday I'll try to get the barrels straightened out and refinish the old gun.
