This is a Jupiteris-made mobile suit that appeared towards the end of Mobile Suit Zeta Gundam. It's one of the so-called Scirocco-designed mobile suits.

In the show, it seemed to be Reccoa's personal unit, but its design is one of my favorites among all the mobile suits in the Universal Century.

This one also features decals, panel lining, and a matte finish.

The large anti-ship missiles were unused in the show, so they're still on the sprue, lol.
The pink parts on the shoulders have been emphasized by attaching H-Eyes. Detail-up parts have been added to the shield to resemble warheads.
