I lived in the bottom pub for three weeks in '68, along with a bunch of other Admin recruits.
The lounge room was above the passage from the snakepit to the street (on the RHS of the photo) and we could hear the screams and running as the more sober ones escaped.
Transferred to Madang which was very peaceful and safe - in those days, before the highway came down.
Thanks for the photo, Descol - memories.
