Wyvern Pens is one of the oldest manufacturers being started by the Finburgh Brother around 1880 in Leicester UK. They sold pens made by other people including Curzon's of Liverpool and then decided to assemble pens themselves and settled on the brand name Wyvern (as one of these mythical beasts appear on the coat of arms of the City of Leicester). The pens were made from bakerlite made to look like reticulated Crocodile or Lizard-skin. The nibs were 14 ct gold. Their nib ranged from rigid to very flexible. They were filled with ink by lever or plunger feed. The first pens they made had numbers but around the early 50s they started giving them names like Consul and Ambassador. Wyvern stopped producing fountain pens in 1955.
