A. Darwin
The likeliest maker of this knife was Albin Darwin (1901-1983). His brother was William Darwin (1897-1957). They were the sons of Albin Darwin (a table blade grinder) and his wife, Emma. The brothers formed W. & A. Darwin Ltd, table blade grinders. It was registered in 1929 (capital £200) at No. 72 Arundel Street. It issued £100 in debentures to tide it over the Depression until 1933, when it was located at Smith's Works, Sidney Street.
