I thought I would never be interested in such a thing as the WWII cossacks in German service...

If someone had told me that, I would have laughed

However... they fought against the French Resistance and the French SAS in 1944 in Brittany. I was planning to build a 28mm traditionnal Breton little village so it could be an interesting idea for some action in it.
So I looked for miniatures but nobody makes these cossacks in 28mm? (Artizan Koschei's cossacks are fantasy).
I can use some German soldiers miniatures because at the end of the war many of these cossacks wore a mixture of German uniforms etc. But local witnesses have written that some of them still had cossack fur caps, large riding pants, etc, and a few still carried their sabre.
