1. There a some ships that in the rules page doesnt have an affilition to any ship manufacturer company (DP-20b Gunship, Acclamator Assault Ship, etc) so if someone wants to buy some of this ships what he/she, should do?
2. If the ships of the question above have no affiliation, that means that if a random player founds a ship producer faction, that new faction would be able to apply for those unclaimed datacards?
I think you'll notice that those ships are either RARE or CP ships. They are not, and will not be produceable. If you want one, you have to convince someone who already has one to sell you it, or earn enough CPs, depending.
In terms of other datacards that may become unclaimed later, it may be possible for new ship production factions to claim them. But currently it is not. The issue is under discussion by the Rules team.
Currently, new ship production groups get no datacards.

I have asked Vey about those ships, since I wanted a few for my CMG..Here is his own words, "No, they are not produceable, nor will there ever be data cards to aquire them." This was towards the Acc, the now GE controled (wasn't when I inquired 3 months ago) ship Interdictor Star Cruiser.
