Taken in about the 1920's this is Williams and Badcock. Their shop was on the Terrace in Market Jew Street but I'm not sure exactly where.... Maybe you can help?

I asked my elderly aunt and she said it was at the top of the Terrace where the jewellery shop is now (formerly Victoria Wine)
One of the things they used to sell was toerag which was salt cod boiled and often eaten for breakfast !
Sounds delightful
