Tui Flat Hut (Gunston's Hut).
Unofficial hut built my a couple of enthusiasts in 1961 (one named Gunston).
2 bunk beds along with fireplace and various pots and pans etc.
Damaged Hut book and some laminated sheets explaining history.
Possums had got in when we visited in 2020 and made a mess (which we did our best to clean up)
