Research Note: Waltham Serial Ledgers designate this run as "Cres. Graden" (Crescent Garden) and 14-Size 3/4 Plate. The "Gray Book" serial lists records the run as 14-Size "F.P." (Full Plate). The full plate model would correlate to the Model 1876. However, observations have been made that confirm these subsequent Crescent Garden runs are indeed 3/4 Plate and should be properly designated as Model 1870 instead of Model 1876. #989915: Verified as consistent with 3/4 Model 1870 [eBay #185798202264].
