WWII Naval Peacoat

This is a legit vintage naval peacoat from WWII (indicated by the label type) and five rows of buttons. Hand-warming slash pockets are corduroy lined. Exterior is Melton wool. There are some small holes in the lining and the upper left button is loose. Last three photos show small holes due to moths in storage, fixable with darning. The chest measures 18 inches pit-to-pit laid flat and buttoned. Coat is 28 inches from shoulder to hem, and sleeves measure at 23.5 inches long. Would fit like a modern Men's size small.
