I was scanning Ebay and ran across a cue that LOOKS like a SW. I know there are many fakes out there running around, but, short an LOA from SW is there any way to know for certain if it is real or not? This cue on Ebay also has letters had written on the joint face/shaft, I think it says PROTO 7 under the bumper and on the joint face and MS on both shafts. Any info here would be of interest.
