To my knowledge there is little interchageability between watches by
different American makers beyond cases.
I do not know of any book on this.
the closes possible exception are watche made by one company for another
such as the Waltham watches made for Howard during the last days of the
old Howard company and the new Keystone Howard operations.
The only other examples I know of iare similar, The Nashua watches
relabeled Waltham, A token number of Hamilton watches they labeled as
Howard after they bought out the Keystone operation, and some Illinois
labeled watches made by Hamiton after they took over that company. This
parts for a Hamilton 400 are interchangeable with corresponding Illini
models.
There is potential confusion with large private labels such as Ball and
operations such as the Burlington Watch Company and the Washington Watch
company.
Surprisingly Swiss watches have a lot more parts interchageability. This
is because they industry had specialists for part escapement assemblies,
called Assortisments, gears, pinions,balances, balance springs, hands,
and dials.
I have not seen catalogs of these firms but there are books like the
"Bestfit Encyclopedia" which identify parts by make model and part
number and identify which are used in more than one model.
Since Elgin and Ball brought in some Swiss made movements there are some
exampls there so I guess in a round about way the book you want s the
BestFit Encyclopedia, which is pretty easy to find. Bestfit was a maker
of parts which they sold to jobbers to resell individually or as kits to
for independents who wanted to have part on hand.
