Well, based on my knowledge, those are Sindy dolls. Sindy herself https://c1.staticflickr.com/8/7114/7612049768_8cb6f0b53b_b.jpgWHile the male doll is Paul, Sindy's boyfriend http://sindy.aluluei.com/history/67-paul.jpgNot sure about the clothes, they may have been made for the show or available separately.I could be wrong about the identities but I'm like 90% sure on my guess.
Superb Lance. Looked at your links and I reckon you're bang on there. the dates fit as well. the dolls wouldn't have been vintage when the film was made. They would have been brand new and not collectable at all. I'll have a look for the clothing as I do like a good search. Thanks for ID'ing the dolls. Its a very creepy film about sorcery in an English village so it was eeerie seeing 'modern' dolls as props.
