        "photo 2: Front closure is a central leather strap with a conventional buckle, not a recognizable vintage Coach turnlock.",

    "possible_model_reasoning": [
        "The compact flap-and-buckle crossbody shape does not closely match the documented vintage Coach turnlock models.",

        "Condition: Good; substantial scratches, scuffs, creasing, and patina are visible on the leather (photos 2 and 7), while strap and closure appear present. Interior condition and odor are not fully assessable."
