Fountain Pen Restoration

I have been collecting (link) and restoring vintage fountain pens since 2016. Over the years, I have received more than 1000 pens for repair, from all over the world, thanks to my free restoration offer that has been viewed on the Fountain Pen Network more than 60,000 times till date! I posted that Pay it Forward (PiF) thread in 2018, but I continue to restore pens today – for a fee that goes 100% to charity (link). 

 

If you are new to fountain pen restoration, then I recommend The Pendragons for parts and supplies, and the following for learning resources: (1) Richard Binder's website or books, (2) Marshall and Oldfield's book, (3) FPN's Repair Q&A forum, and (4) YouTube, of course. If you can’t find what you’re looking for there, I hope the documentation below will be helpful...
