A bit iffy on the Taiidan Bomber part. GMG could be hostile to Rheinland and its pirates but the ship is sold on a Zoner owned station, a Freeport where any sort of pilot could drop in. So its the Zoners who actually deal, bargain the vessel not the GMG those who are the producers of it only. As for the Omicron Delta being out of breach, it is most likely possible for Zoners to carry out the delivery of ships and such orders as they have a vast zone of influence and organization, not to mention the freeports they have across almost the entire Sirius.
I think of the Zoners as the global market of Sirius actually. If they have a grasp of something at their hands, the thing could be bargained with anyone who comes up with a good offer and has decent enough relationship with the Zoners. There are nations in war, as of modern date who provide, bargain weaponry and war technology with their opponents, in a underhanded way or via global networks of blackmarkets. But still, the superior sides always tend, endeavor to keep the best technology available, and the secrets they hold at their sides.
On the uncharted lagoons of anguish, I sail with a canoe made of my sins.
