Sargent   & Greenleaf, model #4 version 2. c. 1884, restoration page 1.

Below are photos of the movement before and after restoration. The movement looks to have been sprayed with huge amounts of oil (probably WD-40) which will in time turn gunky and completely stop all moving parts. Many of the screws as well as the dial hands were rusted and would have to be refinished, polished and reheat blued to bring back the original electric blue luster. Notice the serial number notation of 443. These movements were made individually and every part (excepting screws) was stamped with this number. Since the movement plate contained two individual trains each part had, in addition to the serial number, a notation of 1 or 2 to indicate which train the part belonged to. Even the six movement plate pillars are numbered in sequence.
