The front bulkheads of the passenger module changed through the series. Here are renders of the early version (viewscreen, label placement), and the later version: CRTs replaced the viewscreen in Missing Link/The Last Sunset; the labels change position, and the weapons rack appears in The Last Sunset. It changes again for Year 2, with the fire extinguisher in a new position, new labels, and at the end of the series the label "Weapons Rack".
The front bulkheads of the passenger module originally featured large colour view screens (Breakaway, Matter Of Life And Death, Black Sun, Ring Around The Moon, Earthbound, Another Time, Another Place, Guardian Of Piri). The view screen reappeared (on the port side only) in Dragon's Domain.
From Missing Link the large screen changed to small CRT screens, two on each side. The following episode (Guardian Of Piri) is back to the viewscreen, but the next time we see the passenger module (The Last Sunset) the CRT screens are back and stay until the end of the series.
On the inner side of the bulkhead is a standard moonbase door panel, with signs above. At the start of year 1 there were two sign labels (until Death's Other Dominion). From The Full Circle onwards there is just one sign (the white "Fire Emergency Procedure"). The typeface is Eurostile Bold Extended.
On the door-side of the bulkhead, there is another white "Fire Emergency Procedure" sign mounted low, near a blue fire extinguisher. From The Full Circle onwards this label disappears, with an "Emergency Procedure" label appearing higher, level with the base of the CRT screens.
In year 2 a new red label appears (with a shortened version of the same text as the year 1 label, minus the "codeing" misspelling). In year 2 a blue fire extinguisher is mounted above the label (so the text makes sense, unlike in year 1).
A large red label "Weapons Rack" appears in Devil's Planet and (in a different place) in The Immunity Syndrome.

Beneath the screens were shelves, containing either boxes or spacesuit packs.
The top shelf two shelves on the starboard side were normal storage shelves until The Last Sunset when the top shelf gained a metal rail holding 5 stun guns, and the middle shelf had two front columns with brackets, used to hold a long weapon. This was either a large blaster (The Last Sunset, The Full Circle, Death's Other Dominion, The Infernal Machine, End Of Eternity) or a laser rifle (War Games, Space Brain, Mission Of The Darians, Dragon's Domain, The Testament Of Arkadia, all Year 2).
From The Last Sunset to All That Glisters, the stun gun rack is on the starboard side. From the next appearance, New Adam, New Eve, the stun guns are on the port-side.
From New Adam, New Eve, the stun guns shift to the port-side. Here the laser rifle is also mounted on the port-side.
In The A B Chrysalis laser rifles are mounted on both sides.
In most of Year 1, a blue fire extinguisher is mounted in the lower shelf on the door side. The markings vary through the series- it has normal instruction labels until War Games, when they disappear, leaving it blank.
In Year 2, the blue fire extinguisher is moved above the door panel control, normally with small rectangular label. One of the fire extinguishers is removed by Koenig in Devil's Planet and used as a weapon against the guards.
A "Weapons Rack" sign appears in Devil's Planet on the port-side, above the stun gun rack. In The Immunity Syndrome it is seen on the starboard side, above the laser rifle.
The forward portion of the passenger module contains cupboards and shelves, used for hanging spacesuits or boxes and cases. Theoretically the passenger module could be mounted facing in either direction.
At the front, by the door to the command module, are three shelves. Moving to the centre of the module are three tall open cupboards with hanging rails, which may hold spacesuits or boxes. The cupboards and shelves have red labels over them with numbers. On the port-side the numbers are (centre to front, top) 1, 2, 3, 1 (and the shelves below, 2 and 3). On the starboard, the numbers are (front to centre) 4 (with shelves 5 and 6 below), 4, 5, 6. Obviously there may be some confusion if things are stored in "4".
From Breakaway to Another Time, Another Place there is a green label above the door, with the number "12". Afterwards it becomes a standard "Emergency Procedure" sign.
