Jim asked about recessed straplocks. Dunlop has them but they aren't worth what they charge. Allparts has the dual design style buttons as cheap as garden variety strap buttons. I drilled a 1/2" diameter and deep hole
that chamfer in the hole was actually caused when I screwed down the button.
Butt end of JAEbird II PROTOTYPE, note the nice fat run.
Proto again, location will be a little different on Jim's. I like these BETTER than the completely recessed buttons. The chrome is subtle and provides a better target for the strap, keeps it a little off the body and might possibly take a hit from the straplock instead of the paint....did I mention they were cheap?
