Ok ok... How about 6603... spotted this one on svc 9 couple of
times... i actually meant to write this one as it does not reflect
on sgwiki... i think it is cameo...
6603Y is still SP uh. AM & BN have a tendency to replace
their missing Citaros now with the new 66xx SP Citaros, if going by
the timings of those Citaros. Previously they dumped the SP KUBs to
cover for those cameoing / under-repair Citaros of Sv 9, 40, 354, 6
etc.
