1. Daedalus class starships which were decommissioned in the 22nd century.
2. Andorian Kumari class vessels which were in use in the 22nd century.
3. Maquis raiders which were over 40 years old.
4. Ships which resemble the Centaur type but with extra impulse engines and different nacelles. The Centaur type was based on the outdated Excelsior.
If this was someone’s collection, that would have made some sort of sense. But as was mentioned above, there was no context given for the old ships docked there. The implication being that these ships were active duty Federation/Starfleet vessels.
By the looks of the inside of the station, it was more like DS9 than any standard Starfleet starbase. The old ships could have belonged to anyone (ala: the antique BoP in Picard). Or else Quark is running a used ship business on the side.
