This pen I have found slightly difficult to identify with precision! It is a modern cartridge converter pen (converter supplied) and has a 18k medium width nib.
The cap bands are 2 thin and a thick middle band, which with the size (approx 12.5 cms when capped) makes it, I believe, a 58 series pen - please do contact me if you have a different view.
The barrel is imprinted with The Conway Stewart brand, made in England and 07/125, signifying this is pen number 7 of a run of 125.
Presented in a smart red Conway Stewart box with protective cushion.
