I see .SB used in the C Manual - Language Edited by R.P.A. Collinson Document No: DOC/UNIX.K3.10/1 and UKC IO Library docs also from Collinson at Univ. of Kent. as found in the usenix-78-uk1 tape. Maybe that is uk1.tar at https://www.tuhs.org/Archive/Applications/Spencer_Tapes/ I also see a SB Stymie Bold font in v7 troff.
