To get this back on track of Griswold, Griswold is worth it, yes. The vintage stuff had machined surfaces, nowadays they just pop it out of the mold and don't machine it. It may be a lot heavier too, and that's good for even heat. So yes, it's good to look into vintage pieces. Heavy and smooth. As far as the vintage seasoning, that doesn't really matter, I'm a germaphobe so I'd wash it good and reseason it anyway lol. It'd freak me out to cook in it right after buying.
