I have a blue XL-12 serial# 13411494. OK, This is an 8 digit serial. Am I reading the bulletin correctly? Was my old blue made in 1981? What years were BLUE XL-12s made and What years were RED XL-12s made? Did they overlap? Is there a site with this type of info? I copied this below information from another site.
