Hello, I have acquired a pen which I thought would be rather easy to identify seeing as it had clear and crisp engravings on the side. I thought that a quick Google would enlighten me as to make, age , rarity etc. Alas , no such luck . The engraving says: The "Perfecto" lever self filler. The nib says 14k Warranted and has an ovoid breather hole. That is all I know! Can anyone please help? Thank you
