LEVI'S 503BXX (lether patch, 1 side red tab) No.2

This is a 501xx boys' youth model manufactured from around 1947 after the end of WWII. The red tab is a "single-sided tab" printed only on a side surface. Although it has faded considerably, the leather patch remains solid.The details suggest that it was made between 1947 and 1953, and the shape of the back of the top button and the slightly longer side stitching suggest that it was made relatively early in that period. In contrast to the other single-sided tab, the other single-sided tab, the 503BXX, yellow stitching is used in most places.

The silhouette is nowhere near the same as that of the Great War era; it falls thick and straight. The inseam is also taken quite deep. There is a large roll-up mark at the hem. Incidentally, it has been repaired since it was purchased.

red tab

The red tab is torn and almost gone, but I judge it to be from the single-sided tab era based on other details.

leather patch

The leather patches remain despite being quite faded. However, no characters are readable. It looks quite hardened, but in fact, it is so soft that it may have remained even after the color faded so much. I can assume that they did not use the dryer.

belt-loop

A thicker belt loop attached to the center back seam. The width is 0.55 inch(14 cm), which is the same as the WWII model.
LEVI'S503BXX (leather patch, 1 side red tab)_conceal-rivet

conceal rivet

Iron rivets. The newer ones use copper-plated iron rivets, but there are no traces of peeling copper plating, so it's possible there was no copper plating to begin with. It is stamped "LS & Co SF" but not numbered.

top button

There is a magnet reaction, which appears to be plated iron. The surface is flat, but only the center is slightly swollen.

front-button

There is almost no difference in detail between the 501 and 503B, but you can tell which model it is from the number of front buttons. In this case, there are only two buttons except for the top button, so we know that it is 503BXX.
LEVI'S503BXX (leather patch, 1 side red tab)_flybutton

fly-button

It is likely to be made of plated iron due to the reaction of the magnet. The engraved text is small compared to the top button, and the rest of the text is flat.

top-button (back)

Iron, unmarked button back with slightly puffed out center.

rivet

It is likely to be made of copper-plated iron as it has a magnet. The leftmost rivet is missing. The remaining five rivets have different letter sizes and are a mix of rivets with different specifications. The letter "O" is capitalized.

We can assume that it is made of copper without the magnet's reaction. The blue rust is also quite noticeable. The words "L.S.& CO S.F." are clearly engraved.

side-stitch

The side stitching is very long (about 7.5 inch(19cm)), although not as long as the WWII model(about 9.4 inch(24cm)).
