Troughton & Simms

From Wikipedia, the free encyclopedia

Troughton & Simms was a British instrument-making firm, formed when Edward Troughton in his old age took on William Simms as a partner.

In 1922 it merged with T. Cooke & Sons to form Cooke, Troughton & Simms.

Previously, Troughton had been a sole proprietor, and before that he was in partnership with his brother John.
