[WTB] Grey/Black IBM Beamspring keycaps

[bak3dbeens11]

I’m currently restoring an IBM 3278 Beamspring and am looking for a complete or partial set of keycaps. I’m not particularly interested in white keycaps from another 3278 or Displaywriter. Instead, I’m looking for the gray and black keycaps that came with various models, such as the 5251, 3277, 3101, etc. Additionally, I’m not looking for Selectric keycaps, as they have a different profile than Beamspring keycaps.
