This Adobe Type 1 font provides a good approximation to the rendition of the “important” blackboard bold letters from the old msym10 font, viz., C, N, R, S and Z. (There is a school of thought that believes that msym10‘s blackboard bold “looked better” than that of msbm10, but msym10 is no longer available.)
