Thank you for the input, glad to finally have the answer, or at least the most likely answer!

LOL! Great point Bob, indeed I have never seen a used pair. It seemed like an odd choice as a carry system considering flight suits already had leg pockets. Thanks for the input. Scott 

A very nice uniform for a short lived organization. Where did you find a 15th Cavalry connection? My information source shows the 20th Cavalry was constituted June 3, 1916 in the Regular Army as the 20th Cavalry. It was organized on June 1,1917 at Ft. Riley, KS. On November 18, 1917 the unit was converted and redesignated as the 78th Field Artillery. The 20th Cavalry itself appears to not have been part of the 6th Division, but the 78th Field Artillery was.

We lost a really good contributor and friend. One of the nicest guys you would ever meet. Will miss him dearly. RIP buddy. Dave

It is an original wartime patch.  Value, if you look what they have sold for lately on eBay, they have ranged between 30-85.  Semper Fi - Jeff

Is that one piece (tab is connected to patch)?  If so, that makes it far better than the typically encountered 135th.  

This is an original patch and tab. Value is what you are able to get someone else to offer or what you are willing to pay.   Allan

WWII vintage.   Allan

I would say that this is Pakistani made and in the last few years.   Allan
