I have 4 Ray Schuler cues. That is NOT a Schuler. The insert on Ray's cue was generally made of Aluminum, though I do have one that used brass. The insert should have an outside diameter of 0.440" (all 7 of my shafts are exactly that) and it should protrude from the shaft about 0.32". There is some variance there. The wall thickness on your shaft insert is too thick to be a Schuler and it doesn't extend far enough out of the shaft. The screw on your cue is also too finely threaded. Ray's were/are 5/16" with 14 TPI. The threads aren't cut all the way to the bottom, so they should have a slight flat spot in the bottom between the threads. Ray also designed his joint to give lots of wood to wood contact, which your cue lacks completely. His shafts typically used a single black collar, unless he was making it specially for a highly customized cue, which this cue isn't. I'm talking thousand dollar cues and up, so don't get the impression I'm bashing on your cue. He also used a bumper that didn't thread directly into the butt. His used compressed O-rings to keep it in place. It required a pretty good sized cavity. Based on my knowledge of his cues since the 90s, it isn't a Schuler, but I hope this helps.
