I was only going by what it said on the drawing Neil, can't help that the guy who did the drawings, patterns and castings knew what the item was called but not how to spell it.
The hyphen between Clip-rivit was now obviously meant rivit the clip in place though no rivit is shown on the drawing and only the photos I posted give an indication of that.
I'll probably end up making one as it would only want to be about 1/8" wide
