LEVI'S 503BXX (leather patch, 1 side red tab) No.3

 It's a 501xx Boys Youth model, this one with about 80-90% of color residue. The red tab is a "one-sided tab" and although the patch is missing, some pieces of leather remain. From the short stitching on the side of the waist and the engraving on the back of the top button, it is inferred that this is a relatively old model, even for a single-sided tab made in the period (1947-53 or so). Compared to the other single-sided tab, the 503BXX, orange stitching is used more frequently.
