…so may have missed somone else pointing this out, but the German State Crown looks a decent match to me, including the orb and cross on the top…

Rob
yes, I have pointed in the direction of German State Crown
(it is indeed orb and cross that makes it specific)
but I don’t think it brings forward our search for specific micrometer manufacturer…
Not sure the German State Crown is that different from the others. This is Britain’s St Edwards Crown, made in 1661 for Charles II’s coronation:
Crowns existed before nation states. Back then Europe was ruled by a relatively small number of families who intermarried all the time. Crowns are more likely to be similar than not. Charles II was a Stuart, i.e. a Scot.
British crowns feature the fleur de lyse which comes from our early French royal connections. Our current royal family is distinctly German, and Kaiser Wilhelm, he of the 1918 bayonet crown, was Queen Victoria’s eldest grandchild. Not surprising crowns are alike.
Doesn’t help with the micrometer though. I think spade man, OSKO and the entrenching tools are better leads.
