Parts Data

Part numbers are starting to be available from the ElginTime serial number site.  Here's an example:


If one clicks through from looking up a movement serial number, to the grade details, there is now a link to the parts page.

This new information includes staff dimension data that is a bit messy in linking up to the better known parts data from the service manuals.  The dimension listing are mostly observed "in the wild" as it were, rather than factory specs.
