Vintage Hard-side Leather Suitcase Luggage Briefcase approximately

Vintage Hard-sided suitcase.  It is rectangular overall, but please look at the side view, where you will note that it is slightly rounded at the top, and wider at the bottom.  Two locks keep it shut.  No key for this.  There is no brand name on this. Exterior:
This appears to be leather, with a hard, durable plastic handle.  Minor light scratches on the exterior and wear, as you would expect from a vintage piece.  The metal has discolored over the years; it may (or may not) clean up. Interior: 
The lining is stained on one side, as shown in the photos.  There is a divider that separates the two sides.  The divider has a large pocket on one side that would work for papers for files.  Overall in good condition, except for the top that allows a metal piece to twist and lock it into place.  You will see in the last three photos that it is damaged.  There is a fabric piece that I think is meant to hold your clothes in place; that has a tear in one part, but it still appears to function.
I did not make any attempt to clean this up, or to wash it, as I know that some collectors prefer things to actually look used.  The inside is in excellent condition, but the outside has some marks, as shown in the photos.  They may come off with a little attention. Measurements
are approximate:
20.75 inches wide (left to right)
14 inches tall
5 inches deep (front to back) at the top
6.75 inches deep (front to back) at the bottom Shipping:
I will "built" a box to fit this, using a lot of tape.  The shipping quote is through the US post office.  I will also check UPS and FedEx at the time of shipping to get the best rate.
