I think they were schaller if I remember correctly.if i remember correctly, it had dunlops?
I now have the strap buttons on which I had installed in the mid-80's, which I believe came from gibson - they look like this: <> - but they are buttons, not locks.

I have used black rubber washers from the hardware store, they work pretty well... but look goofy.
