Did you ever find out about your Schon SL-8? I have one like yours with a black w/ red specks wrap. Same "hand cut" diamonds and straight ivory bars unlike the SL-8 's of the actual series. I am really curious why there would be a version with hand cuts and then machined versions. I have another Schon I bought with hand cut diamonds and I can't find a single picture online of anything even close. Anyway, your cue is the only one I've ever found like mine.
