Great find and a beautiful watch!     OD

Wouldn’t it be a 75mm shell based on the measuring tape?

Back from getting a service and new mainspring correct second hand and dust cover.

At the moment looks like I'm about, give me a shout nearer the time and yes we can do lunch. Kev

As the title says, did the USMC use the M-69 flak vest in Vietnam? If so, could you share with me your personal experiences/pictures as I'm trying to put together a Vietnam War USMC display.   Any and all information will be greatly appreciated!

Anyone have anything from Camp Wallace Texas? Thanks

I would def go with antenna pole. The cords are support ropes to hold it up right. If you were in an open area you put up two poles and string commo wire horizontally at the top between the two poles. If you had a tall tree nearby you could use 1 pole for the same effect.  The height of a field expedient antenna and length of wire would increase the range of a radio set over the short whip like antenna.. Youd string the wire through the Gromet on the top pole section. I know a little about this stuff as I was Signal Corps before I was Infantry. The pole or poles are for if, you have nothing else to elevate the wire with.   

That is quite a nice pickup! Congratulations! I read that the US Armed forces still use field phones and wire. Makes sense!  

Hello WWIIBuff1945,   I'm leaning towards tent poles simply because I found that contract listing. Wish I could be more positive.
