This is a boys' model of 11MWZ, I think it was made in 1957-58. Although the target age is 14 years old, the waist is 27 inches, and because of the slightly loose silhouette, it can be worn sufficiently by slender Japanese men. Unlike the youth model 11YMZ, the top button is a snap button, which is the specification of a product for children. The familiar gimmie book is included, as is the adult male model.
