If I remember correctly...
there was someone that posted a similar cue a few weeks or months ago. The design is an almost direct copy of a the McDermott D-4, which can be found at the McDermott website under services, retired cues. Supposedly there are alot of foreign knockoffs of the old D-series but that is the first one I have seen with a logo of any kind on it, kind of makes it interesting, and the other one i saw had a 5/16-14 pin, yours looks like a 3/8-10.
