I recently bought these hats at an estate auction for $5 for the pair (nobody wanted them, so I got them cheap!). I need help in identifying them! They are made of wool and appear to be pretty old. The medal that is attached to one hat is sewn to the ribbon in the same fashion as the WWII military medals. I'm fairly certain the "1972" does not represent the year (I hope not anyway). I'm from Missouri and bought these in Missouri, so maybe the "MO" stands for Missouri?? I THINK they are WWII era hats, but that is why I'm posting them here--to get the experts' opinions!! Thanks in advance and hopefully I can get some info on these two hats!
