Youth version of the Levi's 501/1937 model with belt loops and a cinch back, while omitting the suspender buttons. The ones without cannulae are said to be made in the 1930s, and the ones with cannulae are said to be made in the 1940s, but the ones shown here were made in the 1930s without cannulae. The Another 1937 model is in very poor condition, but the one I'm introducing here is almost completely unmarked and more than 90% of its color is still intact. Unfortunately, the cinch back has been cut and also hemmed up to make it considerably shorter.
A thick straight that barely tapers from the thighs and falls straight down to the hem.
The leather patch has been removed, but the cinchback remains.
back pocket
Almost square back pocket. It appears to have a red tab on top. The arcuate stitch is a single-needle one.
red tab
Red tab with "LEVI'S" embroidery on one side only.
conceal rivet
It's a copper rivet, the same one used on the front pocket and behind the rivet on the crotch rivet.
cinch
Unfortunately, the cinch bag has been cut off. The original owner was probably using a belt and it was in the way.
back york
As with the other 1937 model, the back yoke is stitched over the fabric, which is the opposite of normal.
beltloop
The thicker belt loops are attached to the seams. It's not a light ounce of fabric, but the same fabric as the body.
top button
Clearly engraved iron buttons.
front button
Since it is a 503B, there are three, including the top button.
fly button
Clearly engraved iron buttons, as well as the top button.
top button (back)
It is domed and unmarked.
side stitch
Side stitching on the left and right is longer. In addition, the side stitch threads are thick on the right and thin on the left.
crotch (back)
The lower end has been treated with a cutout.
crotch rivet
The crotch area comes with a rebed. All rivets, including inseam rivets, are stamped with a lowercase "o".
crotch
There is no bar tack at the crotch. This is characteristic of 1930s models, and even 1937 models made in the 1940s will have a bar tack.
coinpocket
The selvedge part is used.
outseam, selvedge
The white parts of the selvedges are quite thick. The hem is unfortunately not original.
fabric
This fabric has a strong sense of depth of dyeing. The slubby feel is also quite strong. There are some neps, but not many.
