This is a rather splendid Conway Stewart No 13 safety pen. Its owner assures me that it has never held ink and is New Old Stock. It appears to be in perfect working order and the chasing is sharp. The only imperfection is in the nib which appears to have been “adjusted” in a manner which marked it.
The nib appears to be original and is engraved, “Solid 14Kt Gold”.
A No 13 is depicted in Stephen Hull’s Fountain Pens for the Million but there is no more information. Was this pen made in Conway Stewart’s factory or imported?
With thanks for photographs and information to Rob Parsons.
