St. Vincent codes?

[kissmyace]

What codes should be displyed on the butt caps of true St. Vincent frames, is there a definative list?

[PrestigeClassic]

A code with a "Q" in it.

Wilson must have a somewhat definitive list, as when you e-mail them with a particular butt cap code, they reply with month of production and factory location. Somewhat, since they seem confused with the really old codes, like from before St. Vincent.
