That's a great question, and the reason I don't want to waste this persons time. It's hard to see how nice the cue is in the photo's. It looks good overall, however the end of the points look not so good. It may be the photo's, but it's putting me off from wanting to pursue it. I could see the guy asking anywhere from $300 to $2000. I'd be hard pressed to offer $400 not knowing what it is....
Of course, knowing my luck, it's probably a Szamboti....
Speaking of which, if it was a well known cuemaker, how in the heck does someone not know what they have?
Unlikely it is Szamboti because the inner points on the photo do not line up. Like Barry has said to another forum member on here, its easy to line up the main outer points but difficult to line up the inner points. Also, Szamboti's are normally 5/16x14 joint pin.
