Another excellent page from Richard Binder, on the workings of the Sheaffer Snorkel. The animation is just wonderful, even if you do have to watch it ten times or so before you can start to follow it. Really lets you appreciate the mechanism in these pens. If that one I bought does turn out to be a snorkel, and it doesn’t work, I have pretty much no chance whatsoever of being able to fix it.
