Reddit mentions of Self Adhesive Brown Paper Tape

No worries! I've found that the brown, paper tape for shipping boxes works great.

Cool sounding project, promise you'll update with pictures!

Googling got me here and specifically to this bit:

So either bust out that xacto knife and start slicing out words manually or pick up something like this and cut strips to cover the text you want redacted. Or use a glue like rubber cement or superglue, and brush it onto the back side of a piece of black construction paper you've cut out to cover the text you want redacted.

Personally, I'd cut the documents with an xacto, tape them to a sheet of black paper, and then run a copy of it and age that document using your favored method. Otherwise what you'd be wanting is a transcribed copy of a redacted document. Remember that documents were usually triplicate or duplicate so an original unredacted version went into a file somewhere, and then the cut-up redacted version was sent out to the clerks and transcribed for distribution from there. Generally by a clerk with a typewriter.
