I think the good brand ones have their names on them, Best, Schlage, etc.. It’s the more generic brands that don’t have any markings, like General Lock, KSP, etc.. Could be wrong, hard to say, there probably are minute differences between them that a real lock sleuth could figure out. Some people want to pay the premium for the brands, others dont. Some people try to pass the unbranded stuff off as the “real deal” though I’m sure.
