Vintage Underwood ink rolls

[although my ancient Underwood up in the attic could easily use “modern” ribbon since the spools remained virtually unchanged on the manual models]

See how easy it really is?

Honey, you can’t just fresh-print up stuff with oldnew ink and pass it off as being 48 years old.

The artifact here is the ink, even pen signature ink the Doctor or Nurse or Administrator used 48 years ago.

Which would probably be three separate inks (pens), as patient chart sign-offs happen not simultaneously... more likely 2 or so hours apart.
