This kit is the Yamato 3199 (3rd Refurbished Version: Commemorative Paint for Participation Medal Ceremony), released as part of the Mecha Colle Yamato 3199 series. It shares the same concept as the previously released 1/1000 Yamato 3199 (3rd Refurbished Version: Commemorative Paint for Participation Medal Ceremony) and does a pretty thorough job of recreating the design specs, with newly tooled runners added to the mix.
At its core, it's based on the Mecha Colle Yamato 2202, with a number of newly tooled parts added on top. A marking has been added to the bow to match the design specs, the rear nozzle design has been changed, and the side mold on the hull has been revised. On top of that, three nozzle effect parts have been added to the back, so there are actually quite a few changed points when you look closely. The gimmicks — rotating gun turret and deployable wings — remain the same as before.
All in all, this is a nicely done precision miniature plastic model that recreates the design specs with a level of attention to detail that almost makes you think "did they really need to go this far?" It's definitely a pretty niche variation, but for those of us who've been fans of the Yamato series for a long time, just having it exist at all feels like something to be grateful for. :-)
