Samsonite Wheeled or Rolling Leather Briefcase or Laptop Bag

Brand new, never used, Samsonite rolling leather briefcase. I didn't put this into play because I fear it is too large to fit under an airline seat in some instances, and I need a bag that MUST fit under the seat. It measures 17x14x8 It's a great bag though, I hate to part with it. There are 2 main compartments, rear has a file folder, front is open and meant for the large laptop case - that case is huge and meant for laptops of yesteryear. Might want to swap out for a slim sleeve. The rear file folder unzips if you want it out of the way. Both compartments have a few small pockets on the inside wall. There is also a front organizational pocket, and a horizontal zippered pocket on the face with little volume to it.
