Approximately 6,000 manufactured by Henry Aston and Henry Aston & Co. circa 1845-1852. This example is dated "1848" on the barrel tang and the tail of the lock. It is desirable for both of these to match. It is also marked with "US/GW/P" the breech, "US/H.ASTON" at the center of the lock, oval "GW" and "WAT" inspection cartouches on the left stock flat, and some small "W" inspection marks.

Very fine with the metal mostly nicely polished to "armory bright," crisp markings, some small spots of faint surface pitting, and minor wear. The re-oiled stock is also very fine and has a few scattered scratches and dings and distinct markings. Mechanically excellent.
