P140 auto-Bannings - In The Lost Canal machines that can find a man, stun him, or kill him according to whatever orders had come from Terra. Carried bionic 'wombots'. Worked by popping in and out of regular space. Wombots - compact and powerful they could carry a body to Phobos and back. Creepy little things, not much bigger than an adult salmon.
Banning-6 - Reliable pistol - Mac Stone owned one.
