504ZXX was a youth model of the zippered version of 501XX, specifically the 27 to 29 inch zippered version with 504Z part number.The 501ZXX, a zippered version of the 501XX, is said to have been born in 1954, while the 504ZXX seems to have been in production since 1952. This one is a "double-sided tab" model with leather patches and red tabs embroidered on both sides, but has details dating back to the early 50's, such as (1)no trademarked ○R or ★ mark on the flasher, (2)no offset belt loop on the center belt loop, and (3)long side stitching as in the days of single-sided tabs.The red tab is said to have been registered as a trademark in 1953, the transition from single-sided tabs to double-sided tabs was around 1953, and the transition to offset belt loops was around 1954-5, so the one shown here may be from around 1953.(However, as described later, the guarantee ticket is marked "FOR OVER 85 YEARS", so it is difficult to determine the date of manufacture.)
