I attended a benefit auction a couple of weeks ago that included one Ruger specialty rifle that is not catalogued and two handguns. The "engraving" on all of them looked like this. One of the Ruger honchos was in attendance and his remarks confirmed that these were specially produced by Ruger for that auction.
However, I guess that there is always the possibility that these guns were sent out to someone else for the embellishment...
