MoR/MBS-E-29 Narval

This mecha design comes from a gargantuan Gundam alternate history story I concocted a few years ago, where, among other things, the Confederacy survived the American Civil War by retreating to the Caribbean and World War II ended with a draw between the Allies and Axis, which leaves the world sort of hovering in a permanent six-way Cold War. I scrapped the whole thing when I realized it was stupid and more or less turning into an excuse to have Gundams fighting Nazis and Confederates and Communists at the same time, but the mecha designs live on.

The naval version of the Soviet Union's Cossack.

Like the Cossack, based on the Zaku and Bolt Gundam.
