A lot of us do. Any one with an interest in vintage pens can not help but run across the numerous second and third tier imitations. As they say - imitation is the sincerest form of flattery. Just know that as you work your way through these pens of the 20s, 30s, and 40s, there will be a wide variety of quality in both barrel/cap materials and nibs. I am sure that you will receive several responses here with photos of various brands.
