Welcome to the Caswell’s Strings RUclips Channel. Caswell’s Strings is one of Britain’s oldest mailorder companies specialising in Instruments and accessories for the Violin family. With roots extending back over 50 years ago in the South West of England and in Bristol, the Caswell’s shop became a household brand under the name Hamilton Caswell’s; known throughout the world for its extensive range of fine instruments and for the largest collection of bows in Europe. Throughout all those years a unique catalogue was sent out every year to players countrywide, and to every school in the land.
