Outer Tower called the “trianglehead,”

The top of the outer tower was officially called the “trianglehead,” with its “lightplate” on top.  But the nickname for the top of the tower was the “meet head” and the plate’s nickname was the “meet plate” because this was the place the three blue legs met.  By stacking several lights on the blue tower’s “meet” plate, lights could be shown to several other stations simultaneously.  Here, a light-keeper stacks and aims four lights from a Bilby Tower enabling four other remote observers to sight on this tower simulateously from different directions.
