Hi Lawyer. The most accurate one I've seen is the Tiger Moth Collection by John Woodside. This was originally designed for FS2002 & updated for FS9. John told me he actually flies some of the examples he modelled & he knows more about the old Tiger than I do. Unfortunately his site seems to be down right now. It's posted at Avsim or Flightsim.com.

There is another FS2002/4 version of the Tiger Moth by Bill Lyons. This is not so visually acurate but I've seen good reports of it.
