The Master-at-Arms Office was an interior room on E Deck.
Purpose[]
It wasn't really an office since it only contained the Master-at-Arms sleeping accommodation, being furnished with only bunks and a wardrobe. It served as the sleeping accommodation for Master-at-Arms Thomas King & Henry Bailey.
Film/TV[]
There are no images of the real Master-at-Arms Office.
It first appeared in the 1997 Film Titanic. However, this film depicted the office as it was on the Olympic, with a porthole for Jack to look out and a cabinet with handcuff keys. Titanic's Master-at-Arms Office was an interior room, so there were no portholes. Either way though, the office is too far back on Scotland Road, and on the real Titanic, Jack would have been submerged before Rose could reach him. Also, despite being on the exterior wall, there are even more inaccuracies. The cabin was not the actual brig, there was no desk or office. As a matter of fact, the "office" was just a cabin with a bunk bed, wardrobe and sofa.
In Roblox Titanic: Reimagined, the Master-at-arms office is just a copy of the one from the 1997 film. Maxine is arrested for being a stowaway and dies in the office.
