Ditty Box Mk1 Open

UN SPACE AGENCY issued Ditty Box, Mark I. Due to limited space in the berthing compartments, ship crews were often assigned a portable storage box with bio-metric lock for personal possessions. These would be kept in storage racks in the passageways and could be taken to any available compartment, such as a divisional work space or common area. Crews were reminded to secure the ditty box while they were in their possession, so two tie-down points were provided on each end of the ditty box. 

Each ship would have their hull number and inventory number on the box for identification purposes.

White boxes with navy/yellow stripes along the oblique corners would be issued to crew.
Gray boxes with green/white stripes along the oblique corners would be issued to transiting colonists.
Gray boxes with yellow/black stripes along the oblique corners would be issued to prisoners, bio-metric lock replaced with a simple latch switch.

Orange boxes with red/yellow stripes along the oblique corners and a red cross inside a white circle are a small medical supply chest, usually found at triage stations. The bio-metric plate on these would be used to record entry.

Boxes are sometimes found in surplus sales.

Internal compartment had a top tray, one inch deep, with a shallow divider for small items.
