The cue in this post is definitely a Cal Hedden cue.
The long tenon going back into the handle, the distinctive joint and several other things are distinctive to Cal's work.
This post compares Hedden's cues to Palmer, Paradise, Mayer and Fedunka, all great old cuemakers of their time but none ever built cues with as much detail and exacting machine work as is done on my Cal Hedden cue.
My cue has been in the hands of many of the best cuemakers alive today and to a man they were all amazed by the creativity and high quality of machining and workmanship.
