Hello pen experts.
I have this fountain pen that I need your expert knowledge to help me identify with the year, model and if possible, the value.
The pen's body has the engraving,
"Caran D'Ache Gold Plated G" - Not sure what G means.
The nib says 18C - 750 B - Not sure what 750 or B mean.
The nib also has a number engraved inside above the screw 255816 - Not sure what this number is.
