Root made the bows for Shakespeare before and after Shakespeare bought them in 1969 IIRC. Bows were marked Root, Shakespeare, and Root by Shakespeare depending.
The Root and Shakespeare bows were virtually identical w variations from year to year in woods used, tip design, and length, etc.
The Root Brush Master was sold as the Shakespeare Kaibab in 1966 for example. That year it had a Shedua riser w a Zebrawood laminate in the center that showed at the sight window and was 58 inches in length. I have a very nice one, and it's still a great shooter.
The Root Game Master and Shakespeare Ocala were very similar and kinda longer (62) versions of the Brush Master/Kaibab. In 1966 it had a Bubinga riser w laminates of Maple and Shedua that showed at the sight window in kind of a striped "butcher block" look.
The Root Warrior and Shakespeare Necedah were virtually identical. I have two very nice 1966 Necedahs that are still great shooters too.
They are smooth, quiet, forgiving, and about as fast as wood/fiberglass/dacron can be.
