I have a Bullseye I grabbed off EBay for $40. The stamping on the bottom says:
STD - 6-S - Designed by John Reuter, Jr. - Acushnet - Made in USA
It also has the Bullseye putter shape etched in with the Bullseye logo near the toe.
The grip is a leather wrapped paddle grip with a Bullseye head and a ball on the end cap.
Does anyone know how old it is?
