Do you mean the One and the Nine? As far as I'm aware, other than for the first six months (during N1's refurb), the Six remained in N1 until 1993 with the One and Nine occupying N2 during the mid-1980s. If so, there's definitely a shot of both N2 sets in one of the behind the scenes documentaries above.

Yes, apologies. I don't think I've seen a photo of that studio when both bulletins shared the studio.

No worries, here's a montage of the studios around March 1988 (from Newsday Revolution).

Clockwise from top left - Daytime summary newsroom set; One O'Clock set in N2; One O'Clock/Nine O'Clock set in N2; Nine O'Clock set in N2; Six O'Clock set in N1; Six O;Clock set in N1.

When they shared N2, it appears the One's set was located in the low-ceiling extension part of the studio, with the Nine taking up the original part of N2 (it's odd how similar the Nine set is to the Six's). I believe that once the Nine left for the newsroom, the One set was reconfigured to the middle of the studio (and possibly enlarged a bit).
