Apropos of the TMP discussion, although it is ambiguous in Viskovatov, other sources describe the Russian cuirassier standards of 1791. Only the borders, including the medallion frames, but not the cyphers, and the fringe varied as gold or silver according to regiment. All other metallics were gold.
The eagle was based on a black silk silhouette, but was heavily embroidered in gold.
The Yekaterinoslav standards were made of orange, azure, and white stuff, in case it’s not obvious from the illustration.
Something I haven’t been able to find is a list of when cavalry standards were issued – or when new ones were issued. I’m aware that the cavalry banners were changed to a standard white (or green) with gold decoration and elements, but during the Napoleonic period, how many regiments actually switched from using their SYW-era banners to this new standard? And which ones?
