I made an FG Primrose specifically for the Gundam Mk-II [Buckthorn] I built previously! "Blackberry" comes from the name of a wise rabbit, as opposed to Buckthorn, who excels in martial arts.
After my last post, I thought, "Buckthorn was seen as a candidate for the next Ausra, so I really wanted to get a Primrose and turn it into an Ausra," but I never expected to come across an FG less than a month after completing it... what a coincidence.
The structure of the kit remains the same, so it can also be made into an Ausra form like the Hazel Custom. The range of motion is slightly narrower than the HGUC, and it has some issues with holding power, but
