Panhandle Slim · Identification

Construction / ID tells

Pearl-snap shirts are the living cultural identity. They do not date a boot.
Boot ID. Look for Panhandle Slim together with Sanders and Mexico marks on vintage tall-shaft or exotic pairs.
No official surviving boot catalog. Seller descriptions and owner-collection examples are pair-level records, not a factory style bible.

Maker-specific markings guidance has not been documented yet. Preserve the complete stamp and compare it against dated sources.
