Back in the 60s and 70s, the blank numbers would have been 1162 through 1166. The SB nomenclature came later on. The rods are basically the same (I don't think that there was ever a SB equivalent to the 1162). Just the blank numbers changed. The 1163 became the 136 2M, for example. The 3M was the 1165, and the 4M, the 1166. The 1164 became the 136 2F.
