Flash gun "whirring".

Hopefully you can see the video here to hear what I mean. http://tinypic.com/r/2ia51n8/6

Taken and uploaded primarily to send to the seller. It was bought as used and tested and in full working order. No bother about that, I'm just curious about what could be wrong?

Does it have a zoom head?
It seems the motor is "disengaged" or something...

I think Luis is right, there's something gone wrong in the mechanical part of the reflector zoom. There's a small motor driving a lead screw to move the reflector to the correct position for the focal length of the lens.
