The unit features notable physical damage to the output drive shaft. As detailed in the close-up images, there are two prominent, deep mechanical gouges / groove scars scored into the metal shaft body, likely caused by a previous set-screw or puller tool. Despite the cosmetic and physical shaft damage, the internal bearing-mounted mechanism still spins completely smoothly and consistently by hand with no grinding or rough spots. The black anodized block housing is structurally solid, showing typical minor handling marks and superficial storage scuffs. The barcode tag "A45259" and inventory sticker "323702" remain clear. The grey control pigtail cable is flexible and securely potted, terminating in raw, exposed multi-conductor wire leads ready for data loop splicing.
