Humar
Brakewell, I realsie that it may be a bit late to be of much use to you, but here's a very small part of the Liwa Hollows 1963 map, showing Humar. The black line is the main track, and a regular patrol route. Below it there's part of a BP map used in the early 70's, just for interest. Humar is marked, 2nd strip, counting from the West in the Liwa. Not a very good scan, I'm afraid.
I hope these pictures aren't too big!
