More than ten years later I have an update.
This cue was made by Harry Sims for Charles "Cicero Chuck" Buban, the "CB" initials on the cue.
As it happens, I bought it from the original owner himself.
@mr3cushion do you know him?
How did I find out? I should have known all along, it was in our original communications about the sale, and I have those records. Somehow I missed his name!
This is part of what I have from those communications in March 2013:
I know Chuck. Haven't seen him for a few years. Hope he's OK!
Side Bar: Maybe once a year I pick my Sims cue and play for an hour or so.
Harry's cues weren't a known for elite construction/science. He had in his mind (contrary to others) on geometry of a finished cue should be.
Screw the others.
He took a lot of grief from the elite cue owners/buyers.
When I pull that cue off my rack I see nothing wrong with how I feel with it. Sometimes I wonder why I went away from it. My answer for that is that Harry told me himself, it was time to move on. He suggested Longoni.
I played with My Longoni for 10 years? Thank you again Deno.
OK so here's why I wrote so much history.
I decided I couldn't live without a Dieckman cue. I found his phone number and called him to order a cue. Dennis didn't work that way. He had his own way with nearly everything. To make a very long story short, Dennis asked me to measure my shafts diameter inch by inch.
Dennis said that's very close to my modified European/universal shaft taper.
