How Many of the TaylorMade r7 Limited Drivers did they Produce?

I Recently Bought the r7 Limited from TaylorMade and I was wondering how Limited it Actually Is.|||not limited at all, its just the model name. it is a great club though, they probably sold thousands, just like they do always.|||Im not exactly sure the amount but they probably just gave it the name "limited" to make it sound good. They probably produced just as much of those as any other club.
