I also managed, through an extraordinary stroke of luck, to acquire a most unusual shave box containing a series of goodies and nasties as shown below. The highlights are the box itself and two Heljestrand razors: one with a barbers notch with a few dents on the blade, excellent honing practice material and an impecable no 4 with broken scales. The DE-stuff is of secondary interest as is the colgate plastic container which may serve as a travel container for a shaving stick.
The box itself is very interesting: on the top of the lid there is an "eight shaped" knob which can be displaced to the right. This allows the top part of the lid to be rotated. You then remove a small wooden cover on said top part of the lid revealing a vertical slot comprising a locking pin which can only be removed if said top part of lid is at 180 degrees from its starting position. With the locking pin removed, the whole lid can be displaced to the right and turned on a hinge giving you access to two compartments. This box was evidently designed to keep inquisitive fingers at bay.
