I have seen several sources which say that this pattern was used by Iraq. I have never seen photographic evidence, nor do I know if this shirt is real, or a commercial copy. Any help would be appreciated.
Nice! I had a field jacket that was picked up in Jordan in the 1990s and is thought to be Iraqi. The pattern and colors are pretty much identical to this shirt. Camopedia also shows the same colors as what you have. I think I've got a photo in Borsarello's "yellow book" on the Middle East, but I don't have it handy.
