This is another version of RX-121 TR-1 Hazel Gundam designed by Papertang.
I posted before a different version of Hazel Gundam made by Rarra.
Featured in the photo-novel and manga Advance of Zeta: The Flag of Titans, Hazel is a Mobile Suit from the Gundam Universal Century time-line.
Based on GM Quel, it is a functional test machine managed by Murphy Team. The main purpose is to test it fighting against Zeon remnants.
This is a hardcore model with many small parts needed to build. It requires 41 sheets of printing paper. The quality is same as a Premium Grade Gundam.
