Cool! 1966?That would be awesome. It's hard telling if these are the same cues but here's a picture from the front page of a 1966 magazine.
Adam was formed in 1969 and started production in 1970.
These cues with the aluminum Heli-Coil style insert and pointed pins were early first run, first catalog cues.
I was lucky to find mine with two original shafts.
