A very good friend of my dads passed away several years ago. He hunted Kenya and or Tanzania in 1970 taking everything from lion to elephant and several plains game species.
The family would like to find out more about his safari. Who he hunted with etc. The hunters name was Loucas Dimou. I know this is a long shot but thought I would toss it out to the folks here on AR.

Unless there was a fire, there will almost certainly be some relevant records in his papers, checks, diaries, letters, etc. That is by far the best chance IMO.
