Balmain Tigers changed, briefly, to Sydney Tigers in, I think, 1995 for a couple of years. Same time as Canterbury also became the Sydney Bulldogs. I also think it was at, or about, the same time Eastern Suburbs Roosters changed to Sydney City Roosters.
All, presumably, to try appearing bigger than what they were in the SuperLeague era and mergers, relocations, and removal from comps.
In the end, "a rose by any other name" proved true and both Balmain and Canterbury, eventually, reverted back (Balmain just before merging with Wests, and Canterbury after becoming just 'Bulldogs' for a bit).
