If I remember right the seller also had a variety of wings with different religious symbols. I'm no expert on wings but these are definitely strange…

looks like a PX purchase type of item. 

I am surprised at the number of replies on this topic. I have seen tons of variations of these patches (some of which you guys have posted on here) online during my own research. I have to say I've never seen this variation before, seems like the dog is completely different than what I got. I really enjoyed seeing those groupings some of you posted!

reminds me of some iranian ided m1s with british MKII type liners in them. perhaps they had some access to m1917a1 type liners as well. 

Got a .32 my grandfather brought home from wwi.

Magnificent!

Thanks Persian Gulf Command.  I am glad that I am not the only one who questions this.

Thank you very much for the information!
