Very nice and rare antique or vintage jewel Salesman travel case. The exterior is made of leather. Also you have its original canvas protection cover.  On the cover of the case, it's marked Brunet 20 Paris which is the maker. Also, at the interior when you lift the cover, it's marked A. Duchemin Paris which I presume was probably the owner's name. 
The travel case measures16 inches long, 10 inches wide and 8 inches high.
The travel case has 6 sections, at the interior you have padding and satin finish. This travel case probably dates from the 50's or the 60's.
Now as for the condition, the leather at the exterior shows some wear, but minimal, the satin at the interior is in good condition, four littles screws are missing, it's easy to repair, the canvas cover seems used, a bit dirtyy but it is in a usuable condition to protect the case. There is no key for the lock. The hinges of each section work well, the two vertical locks also work well.
Very nice case to place collection of jewels, badges, medals or others.

Nice item, good luck in your bidding
