The Master-at-Arms Office was an interior room on E Deck. It was not actually 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.

The only (wrong) portrayal of the Master-At-Arms office: a movie screenshot

There are no images of the real Master-at-Arms Office, and the only film / TV to use the office is 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 lockers with handcuff keys. Titanic's Master-at-Arms Office was an interior room, so there were not any portholes.
