Palitoy treehouse people (Hove Edge HD6)

This is a long shot, but I wondered if anyone out there has the people shown in the picture that go with the 1970s Palitoy treehouse. I've bought the treehouse which I had when I was a child and my parents still had the dog which they've given me, I just need the people. Nostalgia :-) Getting older and reliving my youth again :-) Many thanks in anticipation
