Well,
Decided to scan some of the more interesting illustrations from the book.
The first one is quite well-known and has featured in a number of Maxim-related publications. This is the source of all of them:
These are interesting. Two detail photographs of the Maxim toggle system. Most probably his own hand holding it.
This one was taken while demonstrating the Maxim machinegun to Chinese officials. Most efficient, although a little expensive tree felling equipment.
