Antique fountain pens

[Elmitto]

I m a dedicated fountain pen user and collector since the late 1980´s.
Now I realize I have too many celluloide fountain pens in my collection.
Looking to buy or trade vintage fountain pens from 1890-1915 in hard rubber and/or overlay excellent condition.
For trade I have lots of vintage Montblanc, Parker etc.
I have special interest in following brands:

Boston Safety Pen (eyedropper)
Warren N. Lancaster
Colonial Pen Co.
O.E. Weidlich Pen Co (matchstick filler and eyedropper)
A.A. Waterman (eyedropper)
John Holland
Sterling Fountain Pen Co.


Thanks!
