This TroubleShooter is made from Conway Stewart Heather vintage resin. This has a mixture of aquamarine blues, golds, opal and magenta tones. It is shown fitted with a JoWo No6 medium polished steel nib. It has a yellow metal accent ring at the grip so perhaps a matching coloured nib would be preferred and this is an available option along with others.
The 1313 is a medium sized pen with no step between the 13mm cap threads and the remainder of the barrel. The grip section is slightly pinched to ≈12mm diameter at its narrowest point. As these pens are all hand made there may be small variations on measurements.
Length - Capped = 134mm, uncapped = 131mm
It can be filled with an international standard sized converter or cartridge, and one of each is provided with the pen.
