Here are the 5th Hussars. These are a mixture of Italieri, Strelets, Art Miniaturen, Garrison, Waterloo 1815, Franznap and one or two others.
And here is another Art Miniaturen officer with one of their trumpeters to a flank.
I have taken some liberties converting Austrian and Prussian hussars for this regiment, which is easy enough given the ubiquitous nature of the Hussar uniform.
