Well now doesn't that suck the air out of an argument. LOL!I got bored and contacted NewArt. They contacted ADAM-Japan and they said there is only one 'NagayaSpecial' If its marked '1/5' its a copy. Also said its not a Musashi cue. As posted earlier that line did not come out til 2000. The original was made at the ADAM-Japan shop. They had no info on cues marked '1/5'. I emailed Li at ADAM-Japan as well and haven't heard back.
