Manufactured in the 1830s to 1840s. It is marked with "T-ATWOOD" on the lock, "- -LONDON- -" on top of the barrel, two Birmingham proofmarks on the upper left barrel flat near the breech, and "VI" on the bottom of the barrel and breech plug, back of the lock (under the mainspring), and in the barrel and lock inlets. It has post and notch sights, German silver forend cap, wedge escutcheons, acorn thumb plate, and engraved butt cap; floral engraving on the lock, trigger guard, and tang; and a triple line diamond checkered stock.

Very good with mild aging of the brass and German silver, dark gray-brown patina on the lock, barrel rib, and trigger guard; some light oxidation, a few dings and light surface scratches on the fine stock, crisp checkering, and minor handling and storage type marks throughout. The lock will not lock up at half-cock but is otherwise mechanically fine.
