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 ≈ 139mm, uncapped ≈ 131mm
