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.
I just have to throw this in here. I can't remember where I seen it but years ago someone had a pencil sharpener type tendon cutter. I hate to even say this but I think it was Eddie Wheat. I believe this use to be a common tool for house cues.
