wondering what the age of this USMC ike. I'm guessing the 1950's? Instead of the Corpsman red cross, it has the medical cadusa. A Navy sailor would wear this ike when assign to a Marine unit?
The Corpsman rating emblem was changed to the caduceus around 47-48 if memory serves me right. This patch looks more like a WWII style rate, later ones use blue thread. I'd say yours is probably 1948-Early Korea.
