Its a 1960-1970's vintage Brunswick cue.
They are basically crappy, and have little value.
I have seen guys spend some time and money on them, and they are okay.
They were designed for the "home" market and have an awful joint.
It is not rare, and it isnt worth much. I have used similar cues for curtain rods in my gamerooms.
What else do you need to know?
