Magneti Marelli Generator. Marked Maserati 300S/450S. It appears to match some vintage photos I found online of 450S race cars. Seems perfect for a high end 450S replica, or a spare for an original car. It might be able to be modified to fit other classic Italian cars. Unfortunately I have no history on this unit. It appears to have been rebuilt recently. The cooling fan disk is a bit bent, hopefully it can be bent back into shape if it causes an imbalance at high RPMs. I have not tested the unit, but it spins freely.
Condition: Bent cooling impeller disk. Otherwise very nice cosmetic condition. Rotor spins freely, but unit is otherwise untested.
