My second duty station in 83 I checked into the supply room and drew my field gear. Supply NCO plops down an M1icon helmet and liner. Camo cover was already on it so all I had to do was pop out the head band and put mine in. A few months later while in the field I rubbed my hand across the front and felt something under the cover. So in my spare time I pulled it off and low and behold there were a set of Captain's bars, silver in color soldered on the front. Out comes the bayonet and I pried them off. On the back was stamped sterling silver. I think they are still in one of my junk boxes with dog tags, etc.
