First off I have to say thank you for the excellent detail pictures. I've never seen a Double Oval cue in person, but have wanted one for years based his old brochure. Now I've GOT to get one! Absolutely beautiful!!!
I've known Richard Black since 1999. My main cue collection is Richard Black cues (currently 19). I just wanted to clear up a few points:
Unless requested otherwise, all of the Double Oval cues Richard makes have the same Ivory butt your cue has. The cue butt pictured on his website is identical.
There is no such thing as a "Calender Cue". The numbers on the joint are simply Richard's own cue numbering system. He engraves those on his higher end cues. Your cue was the 10th cue he made in 2003. If you email him asking, he will tell you the same thing.
I wouldn't call it a 1 of 1. But I would call it 1 stunning cue!
