The scavengers

The hood over the forge visible in the top right is in fact the top of an Orbital Manoeuvring System Oxygen tank, hacked off the rest of the tank, fragments of which lie outside. Some of the piping also appears to have come from a similar source: titanium alloy is not usually used for ducting in metalworking shops. No-one, of course, would admit to knowing just how these fragments were acquired.
