But to complete the information:
As far as I know, there are no 2mm figures although, but I have never seen 2mm figures in the flesh, I doubt that you can see the difference between 7YW or Napoleonic figures and French revolutionary ones. But I stand to be corrected.
These ones are from the Adler early imperial French in bicorn range. Other ranges of the Adler series could be drafted in; Austrians in helmet for the 1799 campaign in Italy (although the helmet probably was only really introduced in 1802), German 7YW figures for the 1799 Russian etc etc.
