Gents:
From my limited experience it seems the older the case and rifle the more "stuff" was in the case. I'm sure this was due to the length of hunting trips in the old days and how long the trip was back to the gunsmith. Many old cases I have seen have a complete set of reloading implements and bullet mould(s), complete cleaning accessories, and spare parts such as main springs, strikers, front sight, complete locks (for sidelock and droplock rifles), as well as ammunition. On the inside of the case lid was the maker's trade label and charging and load data.

An interesting side line to these old rifles is to trace the shipping and transit company labels that may remain on the exterior of the oak and leather cases. It is also possible to buy stock certificates from these old companies (gun makers, shipping lines, importers to India and Africa as well as south east Asia).

These things are really cool.
