The "Z" in the model number stood for "Zipper." The following year, production of the 504Z for youths began. Following their success, the 501ZXX, the first zipper-fly model for the 501, was introduced in 1954. This is a reproduction of the leather patch model, an early version of the 501 Zipper Fly model, which is highly valuable among the 501ZXX models produced from 1954 to 1966. The leather patch was only produced for a year before being changed to a paper patch in 1955. Stored in a dark place, but the tag may be scuffed from the time of purchase.
