Working on two pens, a 1946 Parker Vacumatic Major (top), golden pearl (brown), converted to eyedropper fill because of blind cap problem. Fine nib.
And below it I'm re-tuning a late 1930s Vacumatic, with medium nib.
These golden pearls are made of striated celluloid (layered dark brown and clear amber). One of the pens has excellent transparency. Beautiful and sweet-writing pens.
