I bought the clear version from Gundam Base.
MSF-007
The F in the model name is an acronym for the developer, Dr. Fujita, and the performance is better than the Mark II but less than the 100th. 🤔
I read online that it's based on the Mark II, with a Z-shaped head due to procurement issues.
The color scheme doesn't really evoke the image of a one-off ace jet, so even though it's part of the AEUG, the slightly unusual white-orange color and the 🟥 eyes make me wonder if there's something special about it.
