This is the first Fluted octagon newel post I have ever come across, it has a pretty appealing look to it. The Twisted Rail cap has a nice flow to it as it comes down on top of the newel posts.
Here is a good example of another octagon newel post with a octagon upper section where the handrail will die into.
Very traditional octagon newel post and handrail
Nice close up view, nice and clean looks almost brand new.
Nice mix of paint and stained materials in this picture, just a nice design and layout.
