I read in some printing manual that linseed oil inks, when they were heavily skinned, could be remilled and new driers added. If you had some Carlson's ink or something else really good like that, maybe that would be worth exploring. But I doubt remilling a vintage ink could be made worth the time of any inkmaker today.
