Model Description ■ 501XX 1937 Model ■ Silhouette: Wide straight ■ Basic Specifications ● Button fly ● Red ear watch pocket ● Crotch rivets ● Cinch back strap ● Leather patch ● One-sided Big "E" red tab ● Concealed rivets ● Single-needle sewing machine Arcuate stitch Since Levi's obtained a patent in 1873 for reinforcing clothing with metal rivets, their products have gained tremendous support as durable clothing. As time passed, reforms were brought to the exposed rivets that were hammered onto the back pockets from the outside, due to the reason that they would scratch car seats, furniture, and saddles. Levi's devised an innovative manufacturing method of covering the rivets with fabric, and obtained a patent for it in 1937. The 501XX 1937 model faithfully reproduces those details. The back strap and crotch rivets were omitted from 1942, so they are still equipped in this model, and the Arcuate stitch is an old specification that does not cross in the center due to a single-needle sewing machine. Also, a red tab with a Big E embroidered on one side, just like at the time, is attached. The red tab, adopted from 1936, had a Big E embroidered on one side until the mid-1950s. The "501XX 1937 Model" is a model that focuses on the detailed specification changes that came with the evolution of the 501.
