Wild card pen Kit quest.

Is the longer tube (1.975") the upper barrel or lower barrel. Diagram A shows it pressing into nib but calls it the upper barrel tube. Conflicting message to me or maybe it's just me. Thanks in advance for help.

the instructions say the long tube is the lower tube for the nib. the pic show the lower tube is longer.
