thanks for the lost link. I like Ugo's figures, nice small dioramas there.
You are right with buttons, colars etc. And as you say in 1/72 you won't see much difference.
This brings me to the question "How important is historical accuracy"? On the HAT-forum people are talking about the good Waterloo 1815 Polish infantry. In reality they are full of mistakes and in terrible poses. How much does this matter to a wargamer or collector?
