Do you have issue 32 of Black & White Photography? Tim mentions a little bit about Oriental papers in his article about lith printing.

It says:

Japan. Available worldwide. One of the finest, although expensive, enlarging papers made. Lith prints easily and well.

Oriental VC FB: Not unlike the old Sterling lith but slightly less graphic.

Oriental G: (Grades 2, 3 &4) Coffee or putty hues to red-brown in selenium."

Good luck!
