Carol has shared some more of her wonderful collection. The first is a Landico button. I’ve only seen a few of their buttons so far, but they are all cast metal fancy buttons with self shanks. The backs are rough and unfinished, with sharp edges and lumps. This is the first I’ve seen with a (?)painted finish.
Some more Shell Oil uniform buttons.
Carol has guessed that they were from service station uniforms. However, on sites such as Kelly Badges they are described as from merchant navy (in particular oil tankers) uniforms. Service station attendants did wear uniforms; such as a shirt, slacks (or skirt) and tie and jacket. I don’t think they were formal enough to require brass or Stay-brite buttons. And yes, ladies got in the act too!
