Been having fun, restoring and using an old hand-cranked Instructograph - apparently I
have the original ten tapes, plus an extra 11th one too.
Just like many 5-level and 8-level paper tapes I've dealt with, the Instructograph
tapes ("1-level"? 2 levels if you count the flip-over direction) are oiled.
Is the oiling of paper tape, done only to oil the punching machine originally, as the
www.westnc.com<http://www.westnc.com> paper tape page implies? Or does it also help
prevent brittleness and feed around the small diameter rod in playback path too?
