I've been hauling around a great uncle's greatcoat for decades and think I'll actually wear it this winter for once. Am incapable of posting photos but was wondering if someone could clue me in on whether it's likely to be WWI or II vintage-either is possible. It's camel colored, mid-calf length and fits my 5'7 frame perfectly. 5 rows of buttons on each side. Buttons aren't metallic. It's quite heavy. Must be 10 pounds.
