Record the evidence precisely
- Photograph or transcribe all imprints and note their location on the pen.
- Keep maker marks, model names, date estimates and collector attributions in distinct fields.
- Describe nib shape as an observation unless a qualified source identifies its original specification.
- Identify filling systems from visible features or documentation. Avoid testing mechanisms that may be stuck, brittle or inked.
- Record any writing sample with the ink, paper and observation conditions.
This catalog does not identify authenticity, gold content, nib grade, repair needs or safe operation. Ask a specialist before disassembly, cleaning or filling an unfamiliar pen.
Nib and filling notes
Nib stamps can include maker, material, grade, patent and country wording; use a literal transcription and preserve punctuation. Apparent line width depends on nib geometry, pressure, ink, paper and condition, so an old mark should not be silently converted into a modern standard size.
Filling arrangements can look similar across makers and periods. Treat visual classification as provisional. A flexible nib or filling system may be damaged by a writing test or forced movement.
Use a consistent unit and method for dimensions, such as overall nib length or exposed nib length. Explain exactly which points were measured so another cataloger can repeat the observation.
Collecting context: mixed estate pen lots
A current October 2026 antique and vintage pen estate-auction catalog groups fountain pens from several makers alongside other writing instruments, with lot descriptions calling out filling styles and nib markings. That is a useful reminder for catalogers: preserve the exact lot wording, record nib evidence separately from the pen’s maker/model attribution, and keep the source attached to each observation. The listing is contextual only; it is not a valuation or identification authority.
Catalog help
Where are records saved?
Only in this browser’s local storage. They are not uploaded to the website. Export a JSON or CSV backup if you need to preserve or transfer the catalog.
Can this determine gold content or authenticity?
No. It records visible marks and observations; it cannot verify alloys, maker, date or authenticity.
Should I test the filling system?
Not if you do not know its condition. Stuck or aged components can be damaged by force or liquid; document what is visible and seek a qualified pen restorer.
