When the admissibility of other evidence of contents of writings,
recordings, or photographs under these rules depends upon the
fulfillment of a condition of fact, the question whether the condition
has been fulfilled is ordinarily for the judge to determine in
accordance with the provisions of Sec. 18.104(a). However, when an issue
is raised whether the asserted writing ever existed; or whether another
writing, recording, or photograph produced at the hearing is the
original; or whether other evidence of contents correctly reflects the
contents, the issue is for the judge as trier of fact to determine as in
the case of other issues of fact.
