Desire datasheets for obsolete Signetics FFs, Nor

Does anyone have datasheets for LU321A, LU322B and LU380A? I can glean some info from a schematic but some pin-outs are missing and there'll be some tracing to do. Datasheets might be helpful should I need substitutions. They are JK Flipflops w/S-R, JK Flipflops w/R, and Quad Nor respectively.
