I've only got the button bits, not the strap attachment bits but I can pop them in the post of you want. PM me your address if you want them.

However I can also highly recommend recommend these Axetec fully Schaller-compatible straplocks. SPLK05 (complete lock) and SPBT06 (button only) It's what I use these days on my guitars and builds:
