f.a.l. PF 074 Saturno 16 Head Helicopters

Picked up a set of these classic units from f.a.l.!  These are the Saturno 16 head units which are the largest ones f.a.l. made.  Each unit features 16 x 6 volt, 35 watt AR111 lamps (3 degree), although 6 volt, 30 watt 4515 bulbs will work also.  The cool feature about these units are they have dual lamp circuits so the outer 8 lamps and the inner 8 lamps are wired together so they can be run separately.  What is interesting is the motors are currently wired to the inner rings of lights so only 2 circuits.  Not sure if they were modified at some point?  Typically the motors are separate from the lamps if separated at all.  Great units made in Italy.
