Sometimes you can look at something… and all of a sudden things fall into place. Here’s a picture of an American card of buttons; does anything seem familiar?
Yes; it’s the a design used by G.Herring to make Beutron buttons in Sydney.
Around 1940-41 Mr. Marshall Ney visited America to secure the rights to a process to coat non-ferrous materials (such as plastic) with metal. G.Herring (of which he was the General Manager) would used this process in making metal coated “Beutron Originals” such as the above. The company must have also bought the rights to some button designs, such as the cherry one.
