The last entry in the old 1/250 diorama model series is the "Battle of Texas" set, depicting the battle between Amuro and Char that took place in the Texas Colony — a wasteland after losing its climate control functions. This kit includes the Texas stand along with the RX-78 Gundam, Char's Gelgoog, and the Guncannon.
Looking at episode 37 of the original series — the Battle of Texas arc — it actually feels like Magooba's Gyan would've been a better fit than the Guncannon. During the Battle of Texas, the Guncannon was out in space fighting the Dom, while the actual Texas battle featured the Gundam, the Gyan, and Char's Gelgoog. That said, this kit is probably based on episode 38 rather than episode 37 (where Magooba stopped Char from interfering), focusing on the Gundam vs. Gelgoog fight — which is why the Gyan was left out. It also seems like they just wanted to include the Guncannon as one of the few Federation mechs and render it in 1/250 scale while they were at it.
So if you really want to recreate the Battle of Texas accurately, it'd look more right to leave the Guncannon off the diorama stand and just put the Gundam and Char's Gelgoog on it. For old-school fans, it's hard not to feel a little off seeing the Guncannon up there during what's supposed to be the legendary 1-on-1 duel between Amuro and Char.
This kit includes the RX-78 Gundam again — the same one that came with the 1/250 A Baoa Qu diorama set — but this time it's been reworked into a crouching pose holding a beam saber, matching the scene from the show. The small mascot figure, on the other hand, is the same one from the A Baoa Qu set, with only the weapon in its hand swapped out for a bazooka.
Either way, this is a fun diorama series that really hits you right in the nostalgia as an old-school fan, and it'd look absolutely fantastic with a proper paint job. :-)
