It looks like the Gent Jr. pencil is a twist mechanism, not really a cap & post type. I've looked at all the vendor sites I buy from, and have'nt found what you're looking for Chuck. If you do find it, please post it so we can have a look. As far as just a pen, there are alot of kits available that have the cap you're looking for, but just not a pencil version that I have found.
