Having a keen memory bank inside my head, it was jarred when seeing this post. (dug out my books)
Pinseeker was not the 1st company to 'make' metal woods, merely the 1st company to 'market' them.
In 1975 Phil Skrovonsky, with Don Anton & Bob Mader, designed the 1st set of metalwoods, but could not get anyone to manufacture them.
Gary Adams will back me up on this....just call him. 🤣 He and Skrovonsky redesigned the metalwoods for a more 'normal' look. And this design was marketed in '79, with the new company, TaylorMade.
This is what Cwing has to look forward to. Sitting on his ass, researching. 😉
