So, I broke a breather tube off of a feed for my "51"

Anyway to repair this and replace the breather tube with something to make the pen functional again? Or do I need to seek out a new feed/tube assembly for the pen?

Thanks,
Ryan

I think it would be easier and best to source a replacement, should not be too difficult.

From your phrasing, I'm guessing that this is an aerometric pen? If so, don't replace the parts with parts from a Vacumatic-filling "51" -- this means don't use a feed with the short plastgic breather tube. Doing so will reduce the pen's filling capacity greatly and will also destroy its aerometric function. (It will no longer work right on airplanes.)

Daniel Kirchheimer and I have collaborated on an article for the upcoming issue of the PENnant that explains how the aerometric system works and describes the tool that Daniel built for me so that I can fabricate mechanically correct replacement breather tubes.
