Research Note: Rockford Serial Lists designate this run as Grade 64. However, based on similar movements within an earlier run listed as "Grade 46," it is beleived the grade number was transposed in factory serial lists. Additionally, the following run consists of movements listed as "Grade 46" that are inconsistent with the earlier Grade 46 run. It is believed the following run [248,001-249,000] is actually comprised of Grade 64 movements (Model 6, Gilt, 15 Jewels) while this run is actually Grade 46.
