(I have a Craftsman and very brassed Vigilant for that.
I can't tell if it's standard girth or OS, since I just have a slim Balance and a Defender to compare it to. I suspect it's standard. But what's really weird: There is a deeply engraved ring/notch around the rear taper of the pen, about 3/4" in. It looks about like a blind cap would on a vac-fil, but this is a lever filler.
It does not appear to unscrew-- so one could mount a taper and use it as a desk pen.
I have not seen this feature before. Could anyone help me out? My camera needs batteries at the moment, but I don't know how much the picture would clear things up: the ring looks professionally engraved and deep enough that I'd think the end would unscrew. It doesn't, but I don't really want to apply excessive force.
Whatsit?
