The table below summarizes “FAT Numbers” observations already discussed above. It does not introduce new interpretations and will be updated as additional movements are examined. The notations “2DFS” and “3DFS” are recording whether the movement was manufactured with the earlier 2 Dial Feet Screws configuration or with the later 3 Dial Feet Screws configuration. The FAT Number–Derived Identifier, used for internal cataloging and analysis, is comprised of a two-digit model number, the private label name, and the FAT Number found on the pillar plate of the physical movement.  The Derived Identifiers that are bolded are those that were added to the collection after the start of the FAT Number Derived Identifier project and already bear the FAT# Derived Identifier for use on Seth Thomas Fan Space and on the Pocket Watch Database. You can see that five balance bridges, two top plates, and one winding bridge have markings that are inconsistent with the marking on the pillar plate and potentially other components. These balance bridges’, top plates’, and winding bridges’ markings are shown printed in orange below and these components were most likely transplanted from other movements.
