Ronald De la Bere Barker

Also used the name Ronald B. Delabere (and variants).

He was a New Zealander and wrote a book 'Rufiji' about live in Tanganyika. He dedicated it to Clement Gillman. I am currently researching Ronald Delabere and would like to know if anyone can give me any details. He was also known as the Hermit Hunter of Rufiji.
