Hobbs, Hetchins, Holdsworth, Rotrax, Carpenter, Higgins
Here are some in my collection from the 1950's:
My favorites are the Blue Riband and the Carpenter (which is nicely Art Deco). They used to take a lot of care in designing and making these early badges.
There is also an unfinished Hetchins head badge (obtained from the Hetchins' household), which I'll enamel at some point. On the left is an alloy Hetchins badge which is quite rough and may have been a prototype.
