The Ruger ones are pretty rare. I'd only seen one set (the one I have) myself. Heard they were given to distributors only.
Never seen a distributor made set before.

These were done a long time ago. We had these when I started here back in 1998. I'll look around and see if I can find any. I have one I have been using for 13 years on my desk that you are welcome to if you want it.
