Looks Like Russia is the Center of it all, and the others are just the "little people's". Perhaps if the COA were on the eagle's wings, like in the coat of arms of Russian Empire (c. 1883)? I recognize almost all of them except the one at the very bottom (the lion holding the sword) and the blue-red shield between sorbia-lusatia and montenegro. Maybe a guide would be useful? Thank You! Nice Work!
