As mentioned above by DTV, the 1pm and 9pm news bulletins shared Studio N2 from 1986 until 1988, as the 9pm News left N2 in October 1988 and took up home in the newsroom studio N3 from Halloween night 1988.

A small thing, but I don't think the newsroom set was known as N3 during that era - even though it was partially built on the site of the original N3 and a second N3 was later installed in its place, my understanding is that it wasn't really regarded as a separate studio so much as an 'extension' of N2 as it lacked its own gallery (after decomissioning, N3's gallery was initially used as the home to News' graphics engines and was later repurposed as the gallery for WSTV News' studio).
