The price range for a vintage model like the 322 Black & Pearl reaches, depending on condition, from about 100 to 1,000 euros; it depends on overall condition, housing damage, signs of use, discolouration, originality, previous repairs, mechanical defects and rarity. At auctions the individual bidding behaviour and the number of serious interested parties additionally come in. For a reliable estimate, meaningful photos are necessary. The push mechanism of older Montblanc models of this type generally rests on an ink sac; a defective, hardened or leaking sac is a plausible and generally repairable cause of failure.
