For your consideration is this original World War 2 United States Marine Corps wool overcoat.
This has the red insignia on the sleeves and nice brass buttons.
This coat was purchased at auction from the estate of a world war 2 veteran.
This has signs of wear and long storage, such as some rips and moth holes, as well as tears in the fabric lining. One of the buttons has tarnish.
Please see the photos for more detail.
There is no size, but it seems like it is a size 38 to 40.
