Louis Vuitton bag

I'm not sure of the name of this Louis Vuitton bag. It has a bit of a preppy feeling to me. Push lock pockets and a reinforced shoulder strap. Definitely well-loved, it has a lot of aging/marking on the leather parts - straps, etc...Also, there's some tarnishing on the push locks, etc. The corners have exposed frames, but it's not really obvious and doesn't take away from the bag. The interior shows a lot of darkening. Please look at the photos. Any questions, please ask!
