Hi All,
Recently I have collected two vintage Parker Slimfold fountain pens, both made in England. One is black, fitted with a fine 14k nib, and the other is green and fitted with a medium 14k nib (photo attached). The nibs are identical. But their construction is totally different. The filling mechanism is the same for both pens. I would love to know their approximate manufacturing time and which one is the more authentic one among these two.
Please help me in this regard.
Thank you in advance.
