I'm trying to craft a set of items for me. I've created the Bronze Hoplon, Bronze Barbut, and Bronze Mitts. However...I can't find anything else. I see there's a Dated Bronze Chainmail, but no Chainmail. Am I just totally missing something?

I thought if it contained Dated, then it was updated. So please, someone correct me where I went wrong. It seems I'm having a misunderstanding somewhere.
