From the Original Mobile Suit Gundam comes the ill fated Byg-Zam of Zeon Noble, Dozle Zabi. Is it just me?, or does it look like a headless chicken? *snicker*... I guess if the producers of Gundam ever realized back then that the franchise they built would be such a hit, they would have spent more decent time in designing this mecha. The Byg-Zam was released as an SD kit by Bandai in 2001.
Construction Manual for the Byg-Zam was translated to English from the Japanese manual posted at Dalong's Gunpla & Model Kit Review site.
