The first proto made in June, 2002 was called the MW092 PW2.

This Driver may look a little familiar some PGA Tour pros put it to the test late last season. Its a TP with screws called the 510 prototype.

The final proto before the R7 is called the GT4 prototype. created June 2003, 1 year after the first proto.

and here is my early release R7 Quad M.A.X w/ Graphite Design W60 :D

Nice stuff!!!! Quite interesting to see the progression.

Thanks, haribo

Yes indeed to see the different stages it went through is interesting .

Thanks for the pic's Chris .

Wow Cool pix.

I think Justin Rose was using that R510 Prototype with the screws.

Who else was using them?

Awesome pics. Is that the same magazine that has the masters bag pics?

Great pics! Thanks for sharing them. I actually like the r510 proto better than the r7 out now, not as "busy" in my opinion.

Awesome pics. Is that the same magazine that has the masters bag pics?

No it's not. This magazine is April 15th edition, Golf Today. With Toshi Izawa on the cover. At least 15 different monthly and weekly magazines about golf are released monthly in Japan.
