Hi Mike and James
With a bit of hunting around I found the 1915 variant with the red enamel. What I thought was of note was that it bears the backstamp of
Taylor & Challen Ltd. I thought that they were the firm that made this badge but see that it has "
AT" above the name.
I did look them up when I got it but can't recall what they did now.
Suggestion: is the backstamp on that badge that started this thread the address not of the maker but the address of the firm that issued it? Reason also is that I cannot recall such a complete address for a maker before, although H W Miller does this, but at a later period.
Also pictured is a badge that clearly owes a lot to the 1914 Admiralty badge but has the firm's name where the date "1914" or "1915" would be.
Again, I would have noted details of what they made/ did at the time but if anyone wants to save me the trouble of looking them up that would be great!
