Bob, The knife on eBay (291813925338) you refer to also has a W.D. Randall etching on the blade. It also is in the 1991 catalog. I was told the etching on that special Model 10 blade was not authorized by RMK. That is why I returned it to the eBay seller. He is a great seller and returned my payment without issue. I did not tell him why I was returning the knife.

I shied away from the Ivory DP because I feared that etching was also unauthorized by RMK.

Rob, If you care to find out.....you can send your Knife to Joe Dorsky, he may be able to verify the etching on your DP.
