School times past ... any names?

Another one for our 'photo detectives' as Mary Orford calls them ... this picture from a friend of hers needs names.

Mary thinks it is dated from the 1930s, and it probably depicts a class from the Girls National School. Boys studied with the Girls until 2nd Class year, when they went to the Boys NS School, now the Library, established in 1925.

It's a long shot, but some family faces may be familiar.
