1950's-60's leather briefcase

I know its not any newer than that anyway, as I myself came along in the mid 60's and this was *always* my Dad's briefcase the whole time I was growing up. He never actually used it to carry stuff back and forth to his work, instead just to to store 'important papers' of some sort in the closet. [then once I became a teenager I eventually 'appropriated' it, and have had it ever since... ;-) :-) ]

It is made of heavy brown leather, measuring about 18" wide, 13" tall, and 6" thick (expandable). A leather handle and strap-closure and catch both have brasstone hardware, the opening of the bag is actually a hinged painted metal frame. Four brasstone 'feet' on its bottom side. Inside, a single small cloth tag reads "GUARANTEED GENUINE SPLIT COWHIDE // MADE IN U.S.A." but there are no other marks or tags on it. Inside (not shown) are a couple of fiberboard 'dividers' and bottom stiffener.
