There are some questions which I would like to discuss, footwear, looking at the Artaria prints, or an series in AKS Brown - anonymous artist, as well as Reilly, it seems to be boots.
the above is from AKS Brown, see the difference, gaiters at the left hand figure boots on the Jäger.
this one is one of the Artaria plates of 1792 - looks like boots as well.
thanks for your input, and yes I finally came to the same conclusion, so the miniatures I sponsored will have boots.
