Outside of my lone game of Battletech at the Birthday Extravanganza, and oggling the OGRE boxed set, I have little need nor desire to play 6mm (1/285th). However, when something is presented as well as it was by Angel Barracks on TMP, it deserves mention.
Full disclosure: the only thing that's included in the Drilling Rig kit is the rig itself. The storage tanks, building, and vehicle are all sold separately, but it does make a great piece. The rig stand 95mm tall and comes in three parts for around $16.00US
