Pelikan 350 Mechanical Pencil

While recently going through my "treasures", I came across this pen which I brought with me from Germany when I came to this country over 50 years ago. It's been in its box, along with the guarantee, all these years and has never been used. I would love to pass it on, preferably to a private party, and would appreciate any advice as to where I could find any pen/pencil collectors. Thank you!
