This early 7J Bartlett (serial numbers began at 1401) with steel balance became the forerunner of AWCo's commodity products. PSB movements were later offered in 7, 11 & 15 jewel versions. Pinned plates were continued on the Bartlett until late 1858 (around S/N 12,500). The 15J P.S. Bartlett was discontinued by the end of 1860, favoring the 11J instead for this grade. Not clear why the cock on this example is engraved "jeweled." The AWCo porcelain dial is probably not original. The case is just a holder.
