As I understand it, this is a quite rare fountain pen dating back to approximately 1920. The barrel and cap are made of BHCR with a herringbone design. The nib is in very good condition and is marked “PARKER Pen Canada 2” and it writes extremely well. The barrel is marked “George S Parker Fountain Pen Patented Made in Canada”. The Cap Ball-clip is marked “PAT SEP 5 16 PARKER”. This is a button filler which takes up a reasonable supply of ink. The small end-cap (for the filler) is slightly discoloured which is a consequence of its age!
