I can't tell which group that is- however to my knowledge the only groups they went in with the males present (latterly anyway) were Kijo's and Kifu's.
The photo is particularly interesting as shows John Aspinall at an advanced age, still going in with his beloved Gorillas. I don't remember when he died but it can't have been too long after this.
Will just like to add it was a great pleasure, working for Mr. Aspinall, the animals always came first and always got what was required for them to live a happy and content life.
