Nope, no radial construction on this shaft. Blow up the 1st pic and you'll see. I have another precat 314 that has very distinctive lines in it especially closer to the joint where it's clean. The shaft I pictured above is a solid maple shaft I bought from an individual MANY years ago. Any lines you see are grain lines and they are not close to straight like the radial lines would be. There have a been a couple posts where some believe it was probably a prototype 314 shaft that may not have been intended to be sold to the public. It plays well but has a noticeably softer hit to it, (not as stiff) than the radial 314 pre cat I have. Here are a couple other pics of the butts together and the tip of the solid shaft, (and the original pic is #3).
