Levi's Secret Code?

[walletboy]

Has anyone cracked the code on the inner tag of the 501s. I guess they mean something to Levi Strauss company people, like maybe the date of munufacture, the finish and the place and the model (that, I have figured out). I've read the posts here, and while some of the numbers have been figured out (eg, 555 means SF), the rest is pretty mysterious to me. Anyone ever figure this out or can point me to it?

I can recall a couple months back someone was supposed to get the coding from someone who worked there. Never seen it posted tho - Paul T , Serge?

INquiring minds want to know
