JCM 136b??: 1959 Maruten Blue Pitching Back (new variant?)

After finding a number of uncatalogued cards in JCM136, I looked closer, and saw that many of these had a different arrangment of text - namely that the uniform number and school were both listed in parentheses. I am wondering if this is a new set (JCm 136b?)
