I need help identifying this tremolo system

[bdqwerty]

I recently bought a used Fernandes Dragonfly(?). I have no idea about the year of the guitar, and there isn't a serial number on the headstock. There have been some after-market things done to the guitar, but I dunno if the tremolo is one of them. Any help is greatly appreciated.

You might find a serial number in the neck pocket if you're comfortable taking the neck off, or at least a date stamp. As for the trem, it's the right age and matches the hardware so I'm guessing it's stock.
