Enzo rear spoiler motor suppliers - did they change?

Morning all,

have an Enzo here that has had a turn and the rear spoiler has operated by itself on one side. Upon removing the motors to inspect them, I've noticed they are different to another Enzo here. The ones I suspect to be at fault have the company name Maxon Motor on a Dymo style sticker, and don't have a small breather pipe coming off them, or the part number plaque. The body of the motor is smaller as well.

Am just trying to determine if these have been repaired in the past, or if in typical Ferrari fashion they've changed suppliers during production.
