I came across this pen that probably belonged to my grandfather.
First of all I haven't been able to identify the pen or its age. It has a vacumatic fill and an ebonite feed. The ribbed section also seems to be made of ebonite and has some signs of whitening. The biggest problem with this pen is that the barrel has been sloppily glued to the section by some sort of adhesive, most probably many years after the pen was manufactured. The adhesive was quite brittle so I managed to carefully peel it off. What remains behind looks like damage to the barrel itself. The adhesive has dug small pits in the barrel material (maybe celluloid? Bakelite? I'd love to hear your thoughts). Even after the removal of the glue, I can't unscrew the barrel from the section and I'm too scared to force it. I'd really like to know what the pen is made of, how to restore whitening on hard rubber, what parts is the pen made of (threadded, glued) and how one would go about restoring it. I'd really appreciate your input on this pen as I'd be quite interested of restoring it myself.
