Wyvern 690, Black lever-fill, G/F clip and trim. Pencil takes 1.1mm lead
Wyvern is one of the oldest British pen manufacturers, going back to 1880s, so there's a big range of models to choose from. ... Wyvern made excellent nibs, varying from rigid to very flexible. Some of the later pens had very small nibs. The gold plating on the post-war pens tends to be pretty poor.
