Hi there,
dcarty is correct one hole.
Alas my silversmid didn't want to make this into a day-job so I only had several for sale
in a very limited run.
Here's the thread for the pictures, if anyone is interested, of what I think the D-ring+clip
should look like on my vintage graflex ANH lightsaber:

Mind you I still don't claim this D-Ring+Clip to be screen-accurate however I do feel it's
a more civilized solution then your average D-ring attachment.
