In the contrary to the brigand fighters and gunboat, the Courier freighter as well as the l'Ane transport have no Jolly Roger as a mark. Thats intentional and from my side both were generally supposed to be sold who ever wants them and has the credits for. Ofcourse, to see them among gallic lawfuls would be odd, but they should be free to all gallic unlawfuls as well as generic Freelancer, Smuggler and Pirate.
