Pulling the kids in a chariot

This seems to be a man pulling his children along in a chariot, presumably at a fete or fair. There is no date on the slide mount, but the car in the scene suggests late 1960s or early 1970s. The thing most interesting to me is the camera that the man is carrying. Unfortunately, the picture is suffering from a bit of camera shake so it’s not possible to make out exactly what the model is but it looks like possibly an Ihagee Exa 1?
