Okay, I think I should put in my two cents here. First, it is really great to finally see this figure painted - and to such a high standard! Great job Peter!
Second, this figure was indeed based on the series of illustrations of "Cossacks in Paris" by Opitz. It was the stories about the antics of the Cossacks (large, half-wild, unkempt men that were a source of great fascination and puzzlement for the French) that inspired me to sculpt the figure. For example, the word "Bistro" (in French, meaning a small cafe or restaurant) actually originated from the rude cries the cossacks yelling "Bistro!" (meaning hurry up!) at the French waiters that did not move swiftly enough for them. Who knew?
I had very limited reference materials on Russians of the period. The Opitz illustrations were my primary reference source. A set of "Russian Army 1812 Card Sets" (especially sets 3 and 4) supplied many of the finer details for the figure. Any historical mistakes are due to my ignorance of the subject, my limited references and an inability to read Russian, and are thus my fault.
As for the face, he is most definitely NOT Terry Thomas (that was another figure). I needed a sly mischievous grin and I could think of nobody better than my boyhood hero, Ed "big Daddy" Roth. Ed was always quick to mug for the camera and his humorous expressions were exactly what I was looking for:

So, the figure is a portrait of Ed, sans beard and with a cossack haircut!
I bow to svt's superior knowledge of Russian uniforms. Sorry for steering you wrong Peter. However, if I am not mistaken, it seems that changing the color of the tunic to blue while keeping the red facings on the collar and cuffs would set things right?
Anyway, thanks for turning this old sculpt into a lovely creation! It is nice to see.
