From their website:
These are the Greens for our Russian peasant labourers for use in the period 1575 – 1650. They are shown dressed in the same manner as of provincial Steltzi, with forked beards and rustic fur trimmed hats. These miniatures as stripped of their bulky outer-coats and sculpted with period shirts. All are cast open handed to make them suitable for gun crews if equipped with our slight artillery items or as labours if given axes or hammers.
