I'm trying to find anything I can about two estate sale find Levi's. The orange tag pair is a style 646 with a Levi stamped zipper, the other show 515 with a open belt loop style leather label and a Levi stamped zipper. Can someone educate me as to the number code found on the care tag. Does it show mfg. date, plant? Thanks, I'm a newbie and hope to learn.
