I am listing on ebay an item donated to our local Humane Society for resale, a vintage black peacoat with U.S. Navy Petty Officer Third Class machinist's mate patch on sleeve. There is no identification on the coat to indicate manufacturer, fabric content, etc.; only a tag with the size 42L.
Can anyone help me identify this coat?
6-button, plastic buttons with additional button sewn inside and button under collar, partial lining,
