The New Zealand Official History, online, has a nice map of Gazala in December 1941

The online Official History for New Zealand has a nice map of the advance of the 27th MG Battalion to Gazala from 11 to 16 December 1941. One feature of Brazen Chariots is that it is mostly lacking maps. I happen to have a paperback edition that has some illustrations that were added to the original, but the book depends on the narrative, rather than illustrations.
