I was able to partially decode the rubber spec RS-806 AJK.
They've change the prefixes so I guess the first two but they are the type codes. The type R is probably natural rubber, N or S(alternate) was specified next, can't decode second yet, but the following numbers, 806, 8 refers to 80 Shore A, and the 06 is the tensile. The suffixes, AJK, refers to A - heat resistant, J - Abrasion resistant, and K - adhesion. Since it's molded on a steel backer, they need adhesion grade.
