I bought a broad nib a while back. I was told that it was a nib for a Sheaffer Prelude. My plan had been to put this broad nib on a Sheaffer cartridge pen from long ago, the ones that were still made with the hard rubber feeds. Unfortunately, I could never get this Sheaffer Frankenpen to write. It seemed like the radius of curvature of the nib did not adequately match the diameter of the feed.
Can anyone tell me a bit about the Sheaffer Prelude nib? What size is it? Are there any other fountain pens that it is known to be compatible with? I'd like to be able to use what looks like a really nice, broad nib on some fountain pen or another. Thanks for any help on this.
