I like that a lot, and the question about lack of contracts is an interesting one. I do wonder if production constraints had a hand in this, I have seen a fair few used by USN aircrews. Unit purchase maybe, or private purchase or could it be a bit of both. 

Hello Thank you all for your help and confirmation Tony

I REALLY like buckles with airplanes!! and the one above is pretty cool. Here is an Intruder buckle that just sold. Really nice!   VA-95, Green Lizards    

The photo reference I have list both ovals as having an association with the 307th Airborne Medical Company.  

Yup Thai made not German occupation per the seller.

Here's one of them with a close up shot..    

Sorry, I’m out of LIKEs so have this instead… 👍.  That is a beautiful job on the tank!  mikie

I've also used pure tung oil from the Milk Paint Company on my Garand stocks/wood with great results. However, it takes several coats and weeks to cure into a solid, resilient polymer. There are some good websites with instructions on how to use it safely. It's even used a lot for kitchen cutting boards, so it's completely non-toxic and safe, once cured of course. 

WOW, 375 views and not a single opinion....That has to be some kind of record here.  Oh well, eBay can usually determine the price.     Scott

Thank you so much!
