        "photo 5 and photo 6: Hardware is ornate floral metal rather than the plain solid-brass turnlocks and understated fittings typical of vintage Coach.",
        "photo 6: The leather-like body has a pronounced embossed or pebbled texture unlike the smooth glove-tanned leather used on most classic vintage Coach bags."

    "possible_model_reasoning": [
        "No plausible Coach model match: the metal-frame kisslock style and elaborate floral ornamentation are not characteristic of the listed Coach classic models.",

        "Condition: Good\/Fair; visible tarnish and finish wear on the frame, aged or stained lining, and general surface wear are present. Bottom and side condition are not shown."
