AI-assisted summary

Description from the seller

A0000003790

The Montblanc 642 fountain pen presented in this lot shows a very outstanding state of preservation, with an overall elegant and well-preserved appearance, typical of an instrument that has been cared for over time.

The gold-plated cap, with its characteristic vertical striped finish, retains a deep and uniform shine. The surface largely preserves its original lustre, with only light micro-signs of superficial use, normal on a vintage piece, with no visible loss of plating or notable dents. The clip remains straight, firm, and properly aligned, maintaining its original tension.

The black resin body presents an equally very clean appearance, with a deep polish that reflects light well. Fine micro-scratches of use are observed, typical of the passage of time, but without cracks, deformations, or structural damage. The engravings of the model “642” and the “M” mark on the back of the body remain sharp and perfectly legible.

The Montblanc emblem on the top of the cap is in very good condition, with well-defined outlines and no appreciable material loss.

The 14C gold nib Montblanc, engraved with the classic mountain motif and the inscriptions “14C – Montblanc – 585,” is in excellent visual condition. The tines are properly aligned and the iridium point shows good integrity. The ebonite feed is clean and well preserved.

The pen has been inspected and tested, ensuring proper writing function.

Overall, this is a very well-preserved example, with an aesthetically very attractive presence and with discreet wear signs consistent with its age.

Conservation recommendations

To preserve this piece in optimal condition, it is recommended to use high-quality inks specifically for fountain pens, avoid pigmented inks, clean the system with lukewarm water if not used for a period, dry properly before storage, and keep it in a dry place, away from direct light and extreme temperatures. Always operate the filling system gently to prolong the mechanism’s life.

It will be shipped in a courtesy box for proper preservation.

Happy bidding!
