These desks are dark grey, with 5 drawers in cabinets either side, plus two shallow drawers in the central span. Two of them of often seen together; a third one without central drawers appears in Weapons Section.
They first appear in The Last Sunset in the Eagle passenger module. Later in the series they will use a Main Mission desk.
They also seem to be used in the passenger module in Missing Link (in scenes filmed after the later episode).
In Dragon's Domain the two desks replace the seats.
The next appearance in the passenger module is in All That Glisters,where it serves as Tony's bed.
Not clearly seen in the episode, the desk in front of the console in the Weapons Section is a variation, with no central drawers.
The desk against the facing wall in Weapons Section is a standard filing desk.
In The Exiles it appears propped up by boxes in the wreckage of the Area B technical room. It does not appear in the Life Support Complex version of the set in the same episode.
