Richard,
What kind of reel is it? 10.5"? 7.5"? I ask because the other variable is
that is may be a NagraD tape if it is on a 7.5" reel. If it's on a 10.5"
reel it is most likely one of the Mitsu variations.  Unfortunately all
these machines had analog cue tracks, so that doesn't help...
All the best,
-mark
