Hi I am new here so be gentle I have a modern 58 series Conway Stewart fountain pen.It is in a black presentation box with padding and blue ink. On the barrel it says Conway Stewart 300/113 Made in England and on the nib Conway Stewart 18ct Gold M It has a twist ink converter and is a reddish colour. Its never been used (I would like to find out roughly what it is worth before I use it) I got it through a competition win in the 1990s and the little book with it is not stamped or signed. I have tried to research it periodically over the years to find out the colour name and what it is made of in particular but have been unsuccessful so I have signed up here in the hope that someone can tell me how to find these things out. Can anyone help?
