Haven't seen this before, quite an interesting read. Have been reading Bell of Africa, again, and was searching online for information re his date of death as the book says that he had another heart attack in 1951 which proved fatal yet his date of death 30 June 1954. Seems some anomaly somewhere. Anyway the timeline gives quite a lot more information on his life that I have never read before.
