1965: First Adjustable Weight Driver Woods?

[GAA]

1 w, 3 w, 4 w, & 5 w Centurion laminated adjustable weight wood set:

1965 Sylvain F. "Steve" Biltz Jr.  

 1965 Pat. # D206888 custom made for Jerry Helit.

Unusual rectangular shaped head and first known driver and fairway woods

with removable and adjustable brass back weight screws.

 My research is limited, but I have found out that he belonged to the same

Country Club down in Scottsdale AZ as Karsten Solheim.

The laminated woods remind me of sawed off Ping Blond woods. ???

Two heavy brass screws with washers in the back of the flattened head side.

 I am wondering if these were among the first easy to adjust woods?

Anyone know anything about Sylvain F. Blitz Jr. I did find the Patent.

Steve Biltz was my dads cousin. When I was in school, I remember dad talking about the adjustable clubs. Even though they were well received by top players, the PGA said they were illegal. Weird that  I found this thread.

My dad knew Steve and had him make a set of woods for him.  He loved them.  They came with multiple weights (maybe 9?), lead, brass, aluminum,  steel,  and in different thicknesses.

I found a set of these (1-4 woods)  in AZ just a week ago and showed my Dad (now 89).  He's going to take them out and play them for old times sake.
