As far as I can tell. The Tag has a SC number, but I have no idea how to check out all applications. Identical mounting holes are found on other antenna mounting brackets. This one is GI Issue, but I am sure that the shops that engrave plastic nameplates can duplicate them.
Will measure up the tag and post them for you.
