I bought this guitar months ago and it had these strap locks which are different from the usual. Note that the guitar also have a brass bridge and brass nut so I’m assuming this is also brass.

From what I have looked up so far, these look like ones with the locking mechanism where you could attach locks on the straps itself. Can anyone verify? and if my guess is right, where can I buy the locks only itself without the buttons to put on the guitar.
