Nice reproductions of the insignia worn by U.S. Marines during the First World War on their dress caps, or "bell crowns".
Both versions would be correct for the U.S's involvement in WW1, but I have separated both styles for those who need a certain one for their impression.
Featuring the threaded post with threaded washer, and pin to keep the pin centered, these will look great, and will stay on. Only have a limited number of these.
Black was usually for the Forest Green caps, and the Un-Painted ones were usually used on the Dress Blue Bell Crown.
