Navy Armed Guard Patch

[SM Baker]

Not sure if this is the appropriate forum, but, I was wondering if anyone has ever seen an authentic Navy Armed Guard Patch. I found on ebay a patch that looks as if it's modeled after one that Armed Guardsmen may have worn. Thing is, it has "Veteran" embroidered on it, which suggests it was made post-war.

They also have brand new ones:

Obviously replicated, but do any authentic Navy Armed Guard Patches exist?

Thanks!
