Although I was a bit nervous at first with this blank I was a pleasure to see it developing in front of my eyes. Dressed in a Sedona it should have been a fountain pen but I didn't have a gold one from Timberbits which I'd drilled the blank for. I have other Sedona's from the UK and they're different sizes including the threads so couldn't interchange it. I'll get some from TB and it'll become an interchangeable pen.
