We "found" one on the side of what's now Aeroplane Hills at Woodford. A Wirraway crashed many years ago, & 20+y ago bits still remained.
If you want to search, it was south of Aeroplane Hills firetrail, out towards the end, 1-200m(?) off track over a rocky outcrop/ridge. There was a cairn nearby. That's all I remember - it was 20+y ago! We rode in off the Ingar track, but Wenty access is closed. The steep long ways are Andos or Woodford > Bedford Ck > Ingar > AH track
