OK..great. I was going to give you this one but seems like I don't need to.  Your grandfather  left you some nice items. Enjoy and would love to see more.

Thank you for saving this piece of history.

Hello, Russian Bear. Welcome to the forum.   I served in the US Army during the Cold War and was stationed on the Czechoslovakian border during 1974-75. My paternal grandparents were German but lived in Frank, Russia, until 1904. I have ancestors that lived in Frank, Russia, since 1767. I currently have a childhood friend who lives in St. Petersburg with his Russian bride.

This is wonderful act of preservation.    I'm a retired restoration architect and know the wall can be fixed - the graffitti once obscured is lost. I have deep regrets in not cutting out a section of pasteboard wall panel with a"Kilroy" at a 94th Bomb Group base quonset hut, back in 1978 - my first visit to England. The hut is probably long gone and I would have saved a nice piece of a G.I.'s graffitti from the 8th AF.   Here I am at another. I'm thinking this structure (the mess hall) was preserved...or at least the doors, 

Very interesting Considering, I was just reading through a stack of letters from a Navy Carrier Pilot who mentioned he could not write any detail about his unit, actions or a Recent Recommendation for DFC but he was keeping a SERVICE Diary he could share later I  placed an opening bid and if it wins it will be a nice example (service diary) to add with the letter

There was a Leinbach clothing store in Reading, Pa.   Could be where the vet was born, somewhere in Pa.   What are the names of the other theaters?

As P-59A stated, this is the USGI version of the Buck/Phrobis III M9. The 4-line versions are the most common seen, the early production had 3-line markings with different variations. The prices on these Buck Knives made Phrobis III M9's have gone up a lot over the past several years. One in this condition could bring $250-$300 on ebay these days. Very collectible. M9 bayonets are an entire collecting field in themselves.
