I have a few 9314s, but no 2442. I was wondering what I am missing out on; they both look like left foot oblique ("righty") stubs. I know the 9xxx have the osmiridium tips, but this isn't a 2314 vs. 9314 so wondering what other difference there is; I can see the the Falcon has a semicircular pattern on the base, and I have gleaned that it may be a carry over from a dip pen that people were attached to.
