Vintage 50s USMC Military Khaki Chino Trouser Pants 32x33 Cotton Korean War

Super rare USMC Cotton Twill Trousers with hip pockets!! Khaki pants from USMC is really hard to find compared to its of US Army. The closure of this pants is Button Fly, so I assume this is from 50s.

(From 60s it becomes Zipper Fly). Great vintage condition with some black small stains. Other minor flaws may exist because this is vintage item.

Please check all the pictures as those are the part of description.
