Research Notes
1897 BH Catalog: "Full Adjusted" and DS Glass Enamel Dial
All Grade 266 movements are upgraded from original Grade 166 (from 17 to 21 jewels). Two relevant runs are designated as Grade 166 in the 1896 Material Catalog Serial List:
6592001-6593000
6655001-6656000
In the 1904 Material Catalog Serial List, these runs have been split, with some remaining Grade 166 and others redefined as 266:
6592701-6593000: Grade 266 in 1904 MC (2 Consecutive Runs)
6655011-6655042: Grade 266 in 1904 MC
6655044-6655700: Grade 266 in 1904 MC
Grade 166 is part of the "Artistic Series" introduced c.1896, which did not sell as well as Elgin had hoped.
6592001-6592700: Remained listed as Grade 166
6655043: Remained listed as a singular Grade 166
6655701-6656000: Remained listed as Grade 166
