Great flea market find. I am starting to find more and more Vietnam era stuff out of the woodwork. Sadly, the Nam vets are starting to pass in greater and greater frequency. 

Good ol' honest to goodness un-messed with Id'ed WW2 Helmet. Dust it off and place it on the shelf, that's all you need to do. Fun research project.  Congrats.....fixed bales have always been scarce where I am from. Think I only saw two out of the woodwork from the 1980's until Ebay came along and then I started to go to shows. No matter how rusty or if it is missing the chin strap, I still get excited when I find one in the wild. 

Thanks for that information.  Did you get the tube's gun number? Illinigander

PNS = Pennsylvania Nautical School (1889–1947)

I dunno about all the other award, but those marksmenship ribbons at the very end . . . these were usually from time as a midshipman.  My father,  A RAdm with 2 Navy Crosses amongst other award never wore them from 1942 and forward.  He said proficiency with a rifle or pistol was to be expected.  The only time he fired a pistol in anger was at incoming Japanese dive bombers at Midway and a flight deck officer chased him away.    My father grew up in the old army and had been shooting the 1911A1 since he was about 10 years old.  In the mid-1960's when I was about the same age, I used to stop by with my friends at the indoor range at NOB Norfolk after alighting from the school bus and watch the shooters do their thing.  One evening a couple of CPOs stopped by the quarters and told my father I was interested and with his approval they would let me shoot.  He said a couple of sergeants in the 13th Infantry had made the same presentation to his father, then Colonel commanding the regiment,  and were told to go ahead.    So along bout 11 years old I started shooting the 1911A1. Flash forward to circa 1971 at VMI I could take down a 1911A1 without instruction and shoot same with reasonable expectation of accuracy,  They wanted me on the pistol team, but I had better thing to do, like fencing.
