Howdy Charlie and welcome!,
The original white paper micarta known as ivorite in the Randall catalog is no longer being manufactured and has been discontinued as a handle option on Randall Made knives. This material, affectionately known as "Old Yeller" because it yellows considerably with age, was manufactured by Westinghouse as an insulating material. Collectors place a small premium on ivorite Randalls and I scrimshawed quite a few of them back in the 1980s. Randall now offers an "Antique Gold" micarta as a handle option. I'm sure we can get folks to post images of both for you.
