My grandfather fought in WW1.  I am blessed to have his uniform.  I’ve been able to identify most of the items on his uniform but for one pin.  In the attached photo on the left pocket flap is the Victory Medal Ribbon with 2 stars for the 2 campaigns in which he fought.   Below the ribbon, however, is a pin that I cannot identify.   Does anyone know what the pin signifies?  Thanks

Found, Thank you.

This website has most of the Officer Registers. It is not very user friendly though, the registers are not in order and you have to go through them to find the one you want and that can take forever so I will let you do it. https://archive.org/search?query=subject%3A"United+States.+Army+and+Navy"&page=2 

The man’s been dead for decades, just sell the stuff 

Seems cruel to try and contact the family and bring up a death again. It went to goodwill because they didn’t want it!   Keep it and leave the family alone for Gods sake!!!

Too much faith involved.   If the PH was engraved correctly then you would really have something here but without it it seams like a sum of parts situation.

Yes they are military

Lol and not one piece of this stuff is related to Kirk in any way.
