Gladwys Gramophone Supplies and Toilet Requisites

Does any one know anything about "Gramophone Supplies and Toilet Requisites" shops trading at 122, St. Anns Road & 808, Seven Sisters Road Tottenham N15.

They traded under the name "Gladwys" with "Miss Fenn" in very small type. They were also motor coach and theatre agents!

This comes  from a picture of a cardboard record sleeve probably from the mid twenties which I will try to scan and upload.

There would not have been many lady Gramophone Shop owners.
