The cue is certainly a 1960's model Titlist, but who made the cue is the question. It appears to have been made by Brunswick before they stopped production in the 60's. However, I could be wrong because Schmelke started making Titlist cues for Brunswick in the late 60's, so you could contact Schmelke and see if it one of theirs. Around 1969 production of the Brunswick cues including the Titlist Cues was moved to Asia, mostly Japan. The cues that were made in Asia are very easy to identify for the most part because they had a serial number stamped in the wood below the joint collar on the butt and above the joint collar on the shaft that matched. The serial was so that the shaft and the butts would not get mixed up during shipment from Asia.
The cue pictured should be worth between $275 and $400 depending upon how much a buyer wants the cue.
