Canadaicon had some for Trials (whatever we bought with the US pattern barrel mounted flash hider[not discussed in any of the books]), Cuba I believe and South Africa used the same bayo with plastic grips.

Also shipped with the commercial FN-FAL "match" rifles from the 1960s thru the 1980s.

And UZI smgs.

Seeing you in Lloyd this weekend?

I would pull the grips and look for the FN date code.
