Bruce, That is a beautiful, detailed and creative piece of art !!! As some one that does wax carving of patterns for lost wax casting of jewelry, your wax carving and pattern is IMPRESSIVE!!! The pen is beautiful. Do you send it out for casting? I don't think people understand the incredible amount of work that goes into the process. The fitting of the casting any closer to the barrel would require making the wax pattern on an identical width barrel and sliding it off. That's maybe what you did? The clip is also amazing. What do you do to prevent tarnish? Outstanding work!!!! Regards, Doc
