I recently acquired a Swan SW200/60 pen, which the seller claimed was made c.1937. The pen is made from black celluloid plastic with a wavy guilloche pattern. When I first got the pen I had some doubts as to its age, mainly because it looks so new. This got me to wondering: when did Mabie Todd start to manufacture pens from celluloid plastic? I have a Blackbird made from what appears to me to be the same material, but which is much later. Can my Swan really be from 1937?
I must also note that this really has nothing to do with my appreciation of the pen, and is only down to curiosity. The Swan has a gorgeous, broad, stubbish, flexible, wet nib that would have made it worth the price no matter what!

Yup....it sure can. As early as the beginning of the 1930's Swan started to make "plastic" pens. As a matter of fact,some of their
most beautiful colors were made at that time.BTW,your 200/60 code refers to "model type(w/cap ring/band setup)/color code".
