Tallgeese variant that was first seen in Gundam ACE Glory of Losers manga section.
Now this is something! Would like to custom my Tallgeese for to make one of this! Love to see variations like this one everyday.
Seen in Gundam ACE June 2014 Issue: Gundam Wing - Glory of Losers section.
Flugel means "wings" in German
