554ZXX was a youth model of the 551Z, the predecessor of the 505, and the part number of the 554Z was attached to the 27 to 29 inch model. And like the 551Z, it is said to have been born in 1961, and the one shown here is with a "double-sided" red tab and a paper patch with "Every Garment Guaranteeed", so it was probably manufactured around 1961 to 1963. There is a noticeable nep in the fabric.
Even the different design of the flasher and the guaranty ticket is quite different from the 504Z.
With a length of only 27 inches, it looks pretty skimpy. It's not slender, but it's tapered toward the hem, which seems to be from the 1960s.

It has "Every Garment Guaranteed" printed on it. The letters on the part number are large. It is hardened and has already cracked.
flasher

guarantee ticket
It is made of paper. There is a 1960 copyright notice in the lower left corner and "FOR OVER 100 YEARS". Also, the word "PRE-SHRUNK" is written in prominent letters. Not only is the flasher mentioned here, but the 686 process is also mentioned here.
