Not much information, Idk what steel it is (maybe columbus? pretty light), not sure about the date either. But it's cool, EC is cool, steep geometry.

Rides amazing! Feels the same as an aarn. Just testing stuff out, but I am planning to install it again as it's less "busy" than the camo aarn

Maybe I should give the Saturn a try.
I am running a Kappstein Ruphus (that has a quite similar design) and a Factory 5 Lattice.
But the F5 is "noisy" in comparison.

I love it, has a great profile. Reminds me a lot of the No.22 Little Wing, another aesthetically beautiful bike.
