The docking modules are freshly manufactured by some very respectable amigos of our in the Independent Words. They have a completely up-to-date production facility and we regularly collaborate with them in regards to special devices (Docking Bays, Jump Drives etc.). The ones that are in stock on Sanctum were sent as gifts, they were never properly mounted on any ship, so far. You're free to come and inspect them yourself and purchase them if they are to your liking.
