Swan Safety Fountpens

Mabie, Todd. & Co. is a beloved vintage pen manufacturer, having made fine pens, and especially many very pleasant flexible nibs. Their Swan Safety fountain pens were made in a variety of finishes with designs in chased black hard rubber (vulcanite), sterling silver and solid gold.  The smaller E. T. Design even had a ring top for convenient carrying. Some models were quite simple while others rather elaborate. Mabie Todd advertised that their pens that didn't leak and always wrote - the screwdown cap allowing the pen to be carried in any position as it would prevent leaking. Once again, I love the pricing "back in the day" - $2.50 and upward. I would love to find these at that price! Do you have any Swan Safety pens?
