Could not open the photos. I have a Henry Adkin, SLE, 12 30” Damascus barrels, with Adkin’s name on the locks and name-address on the rib. It has SN 182, stamped on the underside barrel rib, and of course both BP and NP BIrmingham marks for 2&1/2” It is lively, handles like dream, was little used, with original case color, clean bores, and barrel brown. My understanding of Adkin is that they were a provincial maker and manufactured around 2000 guns, SL and BL. Whoever ordered this must have wanted above average wood because the stock is honey colored and smokey with distinct mineral lines. Weighs 6 Lbs 5 oz.
