This is a ship from the game Einhander. It's actually somewhat of a mix between the Astraea FGA, Mk. I and the Endymion FRS, MK. III. The head is closest to the Astraea fighter, and the rest is closer to the Endymion. The Claw works and can hold onto weapons.
Hey, I remember that game! The original hover-gunship-type-thingy! This looks great! I'd love to see more of this kind of thing on MOCpages, especially in minifig-scale. Great work on all of your Einhander MOCs!
