This company was registered in December 1954, and may have taken over ‘Delphi’ and ‘Cygnet’ at that time. Previously registered names of the company that from 1991 has traded as ‘Bertram Pacific Pty. Ltd.’ include ‘E. Walker & Son’ (approx.1966-1981), ‘Walkers Fashion Accessories’ (approx.1984-5), ‘Walkers BHS’ (from 1986), and ‘Bertram Fabrics’ ( 1979-1991).
I have not been able to determine whether they manufactured buttons themselves, or only imported and distributed buttons. In 1981 they were selling costume jewellery, handkerchiefs, belts, buckles, buttons and sewing accessories.
Cards exist of both Walkers and Delphi buttons described as ‘A Delphi Product’. Delphi was only advertised in 1954.
The box below shows that Delphi was merged into the Beauclaire line of buttons, similarily to Leda buttons. The name ‘Delphi’ was phased out but ‘Walkers’ continued into circa the late 1960’s, (presumably used by Beutron who bought out Beauclaire in 1957).
E.Walker & Son were distributors of Korbond products in they 1950’s. The buttons on their cards above and below were probably distributed (rather than produced) by the company.
