Research Note: Factory records indicate this run should feature 11 jewels. However, #1552217 has been verified as a private label marked "Wm. Barthman - New York - T - 12 Jewels." The upper center wheel on this movement is clearly jeweled [eBay #334379572542]. Other movements in this run have been verified to be consistent with the 11 jewel count (no upper center jewel).
