I'm not that familiar with all of the Zoner bases, but it seems to me stuff sold at the Freeports would be pretty much open to purchase, while stuff sold at (how many?) other zoner bases would be considered for zoners only. Not sure if that works because I don't know how many non-Freeport bases they have or what is sold at which bases exactly.
I've encountered some Mini Razor armed ships of late that made me scratch my head is all, wondering how free they were to various factions. Looks pretty wide open to me.
