There is a company in Illinois which took Schuler Cue's inventory when Ray died. They had a single butterfly listed, but no doubles. I've only seen a single butterfly in person and only one of those. It was in Ray's shop at the time. I told him I didn't know he made those. He laughed and said he made a little bit of everything. There aren't a lot of them floating around. I looked at your cue every time it came up. I already have a fancy Schuler and can't justify buying another, or it would be in my case already. I'm glad it found a home.
Ray had a catalog which included about a dozen or so cues he made repeatedly, but he also made lots of versions of each and a lot of one of a kind cues. I got to see 'The Czar' cue and a Cuelmanns cue. They were gorgeous.
