On shoulder of sleeve is a button epaulet. There is a well stitched repair on the arm, see las t2 photos. Also if you look closely the color is a little darker under the arm, no doubt from perspiration. Really good vintage condition historical shirt. Color is more of a dark olive green than some of the pictures show.
I researched the patch that was on the shirt, as found, and it is a WW2 25th Corps Tropic Lightening patch. Underarm to underarm 19 1/2 inches, sleeve top to cuff is 23 and length measured from center bottom of collar to bottom of shirt down the front is 31 1/2 inches. WE SPECIALIZE IN UNIQUE ITEMS!
