Yes, you see them on occasion, but not a standard issue item. Below is a USN nightfighter pilot from VF(N)-90 aboard USS Enterprise in 1945 and a USMC PBJ pilot from VMB-611, also in 1945. 

I remember reading about this years ago. Same thing with the Corpsmen. Originally, they had matching sets. 2 crows, one on each sleeve, eagles facing front. But they were told to split the pairs and wear them on the left. That’s why you sometimes see Corpsmen crows vs on Marine uniforms, facing to the rear.   While I have seen Marine uniforms with only one chevron, they are pretty rare. Guys just went to shops off base and got the second one

This is the story of the Rose-Bailey wagon train. They encountered the Mojaves at Beales crossing in 1858. This triggered everything that followed. https://mojavedesert.net/mojave-indians/us-04.html

Thanks Kurt. I think I found the threads you and FFZ you are referring to. Interesting that there are others out there and explains the variation.  Steve   https://www.usmilitariaforum.com/forums/index.php?/topic/266342-audie-murphys-bronze-star/#comment-2142326   https://www.usmilitariaforum.com/forums/index.php?/topic/204188-audie-murphys-medals-strange-looking-bronze-star/#comment-1598158

As a Chaplain collector I don’t believe the Chaplain had their on patch. They did use the black piping cord.

Hi Dom   I have a few WWII and 30s officers and enlisted submarine qualification notebooks.  They show up in complete groups.   Cheers Josh

Not good.  Muted details and looks cast on reverse.

Patches such as these continued to be made and sold to the collector market well past WW2.  The embroidery was pretty much the same as the WW2 era patches, but the materials changed to synthetic.
