This is a mint and un-used Pelikan fountain pen. It is the a prototype for the limited edition 1935 model. The pen has a jade green cap and barrel, and gold plated trim. The pen is a piston filler (working and never filled). The nib is 18K gold, and has a medium tip. This pen is stamped with the number “0000/0000” on the cap. It is from an estate collection of a well-known collector, and the auction catalog is listed online with provenance. The pen has no box or papers….being a prototype, it did not come in the 1935 box (may not have been designed or produced when this pen was made). I believe this pen may be one of a kind, and is guaranteed to be original and un-altered factory product. Certainly a pen for the future that will add amazing depth to any Pelikan pen collection. Buyer pays shipping, $15 in USA. Thank you.
