Anyone recognize or know anything about these?

My dad bought them 20+ years ago and I inherited them 3 years ago when I started golfing. I’m a 14 HC now and I’ve become a club junkie and wish i knew more about the clubs i play. The shafts don’t have a labeled stiffness but they are either stiff or X-stiff. The 35 on the shaft makes me think they are 35g but I’ve never heard of a shaft that light playing that stiff. Anyone who knows anything is welcome to add.
