This makes me wonder about reweight dates and location codes.
Weren't cars to be reweighed every couple of years? If so,
wouldn't "foreign" railroads reweigh other railroad's cars if on
their properties at "reweight time"? If so, wouldn't one
see "foreign" reweight location codes on some cars? Perhaps I'm
mistaken and only owner railroads would reweigh their cars which they
could only do when their empty car was on it tracks.

Yes, yes, and yes. Cars were also reweighed off-line whenever repairs
were required which might change the light weight, such as replacement
of a wheel set or truck. Cars were usually re-lightweighed by their
owners, but there were certainly plenty of exceptions. A fairly
comprehensive list of reweigh station symbols for all RRs is in the
STMFC files, and decals have been produced both by Champ and by
Sunshine.
