What we have here is a paper model of Mobile Suit Zeta 010 ZZ designed by papercraft designer June from Japan.
I’m assuming she/he is from Japan since the instruction guide it came with is in Japanese. This scale model is a Zeta that has been upgraded and has a lot of armaments. Among it is 60mm vulcan gun, high mega canon, double beam rifle, hyper beam saber, missile launcher and shields.
It is piloted by Judau Ashta.
The size or scale of this gundam is 1/60. Building difficulty level is hard and requires 41 sheets of paper.
