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
Interesting info about the clip screw. How do you access the inner screw? Looking at mine, I don't see any way of accessing the back side of the barrel.Looking at mine, both screws are fake on the exterior. The clip is tightened by a screw on the inside of the bolt. It does come loose over time (I hook the clip on my jeans, so maybe putting more stress than other people might), and takes using a long and fine screwdriver to tighten it back up without disassembling the body.
That said, I've only had to do this two or three times since I made the pen back when the kit was new. Overall, I'm happy with it and would buy it again.
