Another trig being refound from an earlier hunt back in the 1980s. Found then 1218, Wednesday, 27/6/1984. I didn't have any success with either Barbara or Beaumont trigs then.
Back in Sydney for a short visit I stopped off at a house that our family lived in just up near the end of Beryl Avenue (Flinders Place. Memories.
Today I found the PM box style trig @ 1850, with a name plate on the inside of the lid. I tried to dig down to a pin or other marker, but it seems that nothing is close.

Rated: for Overall Experience.
