Hi
I had meant to post this following our recent exchanges (and may have indeed done so before) but thought it might be of interest.
The firm that made this badge was set up in 1921 so it may be reasonable to assume that they produced this badge shortly after this. I've only ever seen
two and I bought one of them!
They seemed a little confused as to whether it should be a Queen's Crown or a King's Crown and when I went to count the dots/balls or pearls I went cross-eyed!
