I couldn't really find anything about accidentals in combination with clef 
changes in Stone or Read. The only thing that might apply is in Stone (p.54, 
item "D. At Clef Changes":
If a clef changes withing a measure and the same note occurs before and after 
the clef change, the accidental must be repeated:
(Example in lilypond-notation:)
\relative c'' { \time 2/4 \clef "treble" a8[( cis,]) \clef "bass" cis[( e,]) }

In that example, the cis after the clef change gets a sharp. 
However, this example is only about repeating an accidental, not about whether 
all previous accidentals are actually reset and no natural is required.

As a musician, I would definiely appreciate if the natural sign is displayed, 
just to make it clear that it is a c and not a cis.



I would be great, though, if anyone can find a published example of such a 
situation (most likely in e.g. cello/bassoon parts/scores, which frequently 
switch between bass and tenor clef).

Cheers,
Reinhold
