Great find Dave, thanks. The Koa pen that is the first on the page is exactly the same. Now if I can only find out where he gets his parts ...I saw very similar ones for sale at InoOf100Pens, a California based Etsy store. I saw them in both Brass and Black in the $60 dollar range for completed pens. The store called them "Industrial" pens. I haven't found any kits anywhere that look like these though. Maybe the Etsy shop owner would be willing to give you some information. - Dave
