Maybe you can track it down. He may remember who bought it. Who knows.
I'm surprised Richard didn't come right out and say yes/no to building it. Maybe he wants it in hand or I guess it's possible he charges like Schon does now.
I guess this is a pretty obvious answer, but has anyone tried contacting Richard?
Although it doesn't look like a Black to me, I've not seen many pictures of his early cues, and none in person.
