I've lost the barrel of my favourite EDC pen: my Platinum PTL-5000. I (used to) keep it in the pen slot on the back of my Hazard 4 Badger ID card holder, and one day the barrel came unscrewed and disappeared without me noticing :-(
I can't find replacement barrels but have an interesting "Frankenpen" question to solve my problem. I can get a Platinum Maki-e rollerball slightly cheaper than buying a new PTL-5000 fountain pen (http://www.andys-pen...ting&order=DESC). Does anyone know if the sections are interchangeable between the fountain and rollerball pens, ie - can I use the barrel from the rollerball with the section / nib / converter / cap from my fountain pen?
Thanks in advance if anyone can help
