A customer ribbon group by Studley, Avon, NY for an Army enlisted man who served in Europe in WW2 and the Korean War. Who can tell me the id of his foreign decorations?

Wwii

It is an Army contract medal. 

Looks good to me but I don’t have it in hand. Not much information because they are a cumbersome difficult item to put your gun in and in a war why would you want your gun zippered up in a case?  I’ve had one before, I did ok on it but not as much interest as I expected. Kind of a dumb thing to make really in my opinion 

I’m with @KurtA, on the low end.     Sorry, but just too many things that don’t make sense on this one - in my experience and opinion.     I’ve spent many years collecting WWII USMC items, and have seen scores of marked-up seabags.  Everything from simple stenciled names / MCSNs to elaborate paintings, and this one isn’t convincing to me.     “Hawaii” was painted on this bag at the same time Guadalcanal and the rest of the locations were.  To follow your (OP) hypothesis of a hospital paint job:   Where did he get all of the colors of paint?   Why the need to redact / repaint UNIS three times, as his unit would not have changed by then - and, he’d have been in ‘permanent’ possession of the bag at this point.  So why put an encrypted unit ID on it, when the 3rd MARDIV SSI is boldly emblazoned on it?   Why are there dark stains througout the bag - especially the bottom - but the paint is bright and fresh on top of the discoloration?   Why is the name applied in uncommn syntax to period USMC convention of first init, middle init, surname?   Again, all just my opinion.      

Google lens is your friend.  

If some buys this thinking it’s original good then they get what they deserve.  I saw the auction and the poster used AI to write his description. 

Diamagnetic. If anything, it's repelled by a magnet. https://en.wikipedia.org/wiki/Zinc

Zinc is attracted to a magnet. The 1943 one cent is the only US coin ever made that is attracted to a magnet. 

After 50 years of collecting military items I have never found a pair of these.   Guess the squids used them post war. Rare in my opinion, not sure if that equals value as Navy stuff always seems to be dragging in the military market.
