Mrs Walker, of South Launceston, was given the doll, that is dressed in a Broadland House uniform, as a gift for her birthday in June.

Ever since, Mrs Walker has been on a mission to find out more about it.

"We've tried all over the place to find out where it came from and a little bit about it's history, but we kept drawing blanks," Mrs Walker, a former Broadland House girl, said.

A friend of Mrs Walker's bought the doll from Armitage Auctions, but the women have no clue how it got there.

Mrs Walker estimates Marjorie - who she named after the "lovely headmistress" she had when she attended the girls school between 1957 and 1960 - would have been made sometime between 1920 and 1930.

She said the uniform was similar to the one she wore, except the hat was different.

Mrs Walker also worked at Grammar for 12 years doing office work and often went back to the junior school, where Broadland House still stands.

Broadland House Old Girls Association president Dona Bradley said the doll was very special.

"You don't see dolls like this anymore," Mrs Bradley said.

"To think that somebody had gone to the trouble all those years ago to make the uniform and the doll, it's sad that we don't know anything about her."
