The case exterior cleaned up quite nicely, and the interior vacuumed-out quite nicely.
The case is now sound and has the appearance of a well repaired period / era correct case.
Items that were not done due to essence of time:
--- Hinges and latches corrosion was not masked-off and brushed.
--- Hinges were not oiled (time required to allow and wipe off oil runs).
--- Blow out repairs were not repainted to match the surrounding covering.
--- Leather lid stop brace should be wet with a leather refresher or flexible glue such as water soluble and thinned vinyl
glue or water-based and thinned vinyl repair paint used as a wet soak reinforcer.
--- Miscellaneous broken short hem thread runs were not reglued underneath as is common repair for same;
Although a luggage repair shop could re-hem those broken threads, most likely after also glueing them down.
