Last of the repaint 'Mechs I have so far, it's the Lyran Guards from the Lyran Commonwealth. A pretty popular color scheme and I can see why. The cyan and white really pop.
The Lyran Commonwealth is a German-coded faction with a heavy emphasis on mercantilism, to the point where their military suffers from "social officers" - officers who merely buy their ranks and positions, rather than based on their quality. At one point, the Lyran Commonwealth joins up with the Federated Suns to form the Federated Commonwealth, becoming the dominant power for awhile. War and internal divisions inevitably lead to them breaking apart, though.
I'm really happy with how these turned out, though. Very crisp. Some of my best work with any minis.
How old are those even? I remember getting the starter edition in polish in 1993 but those were already plastic ones (though pretty bad)
The metal ones are new. The molds are retro. Iron Winds Miniatures, I think, is the company.
