This is the Messer M01 from Mobile Suit Gundam Hathaway's Flash.

The M-type (Moriki version) was manufactured on a different factory line than the F-type (Fujita version), and is closer to the original design from the novel.

The internal frame seems to be the same as the F-type, but the exterior is completely different.

Gauman's unit is depicted as having an exposed metal part on the left shoulder because the painting wasn't finished in time.

This is a straight build of the kit, with partial painting of the armor undersides gray and the thruster interiors yellow, using the molded colors.
