In the Angolia book it is classed as a Fire Defence officer for Hannover in bronze
Nice one Ben!.......
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.

Ben thank you very much. Turns out there were several types of buckles Hannover.
I have in the past tried to find an unequivocal identification for this particular coat of arms, but have come to the conclusion it could be either for the (Prussian province) of Hanover or the Freistaat ("free state" of) Brunswick/Braunschweig.
Both have the "Saxon horse" (Sachsenross) as their emblem, and both were historically ruled by branches of the Guelphs. The formerly independent kingdom of Hanover became a Prussian province in 1866 after finding itself on the losing side of the Prussian-Austrian war of that year. The Duchy of Brunswick remained an independent state under the federal constutions of the Empire of 1871 and the republic of 1919, but now styled a "Freistaat".
The arms of the Freistaat Braunschweig are described as "the white Saxon horse on a red background" ("das weiße Sachsenroß auf rotem Felde") in Art. 1 of the constitution of 6 January 1922, and I have not found any official texts providing a more detailed description. Thus, there was considerable scope for artistic license. Attached are two depictions of the arms purporting to have been drawn from official documents, and these would both sit well with the buckle's design. Also compare the Braunschweig buckle on the Assmann page, which is very similar and mainly differs in the style of shield.
The provincial coat of arms for Hanover is officially depicted with the crown, and the horse is usually prancing rather than running (as shown on the Assmann page), but it is entirely imaginable that the crown was intentionally left off here, and there are historical depictions of the running horse for both Hanover and Brunswick. And to confuse matters even further, I have found a depiction of the Braunschweig arms with a crown, and a prancing horse, also attached! Main distinction from the Hanover arms seems to be the more elevated horse's tail. Unfortunately, I didn't save the source of that one.
On gut feeling, the case for Brunswick may seem stronger here, but Hanover is a decided possibility as well. Sorry for perhaps just adding to the confusion!
Kurt Thank you for answer.
