Complete Fighter's Handbook, and reprinted in Dark Sun.There was also piecemeal armor rules in some 2E book. I forget which one. Maybe the complete gladiator's or fighter's book. I don't remember where, but I remember using it.
They'd be hard to transfer over to later systems, because 2e basically only cared about AC and weight regarding armor. Later editions get a little more detailed with things like penalties to certain checks, limits on how Dex applies, and so on. Also, some of the armors are essentially pre-made piecemeal armors – e.g. breastplate "consists of a fitted metal chest piece worn with supple leather."
