Harley Knucklehead UL Flathead Panhead Old Chrome Primary Cover For Sale - New and Used

This is a genuine factory original OEM Harley-Davidson stamped steel "tin" outer primary cover. This rare legacy part features the classic structural diamond-stamping layout centered across the main body channel.The cover features an old chrome finish that has developed an incredible vintage look over decades of storage. It is configured with the traditional early rigid-frame styling, featuring the large open rear clutch inspection hub circle profile and a two-bolt center inspection window.Condition Details & Discrepancies:

• Aesthetic Finish: The vintage chrome plating shows heavy signs of age, including widespread surface pitting, dulling cloudiness, scattered fine hairline scratches, and specs of active flash surface rust detailing. It has an excellent, authentic patina perfect for a survivor build.
• Structural Integrity: The heavy-gauge stamped steel backing layout is completely solid and straight. The outer perimeter sealing lip and all factory mounting screw holes are fully intact with no tears, cracked mounting eyelets, or previous structural weld repairs.
• Interior Casing Condition: The inner face is structurally sound, showing a dark layer of old primary oil film shading, natural surface rust scale patterns, and old gasket sealant residues. It can be run as-is for a true patina build, or serves as a perfect core candidate for media-blasting and a complete re-chrome or gloss black paint restoration.
