Check the photos.  In my opinion, everything is good, just vintage.  I'm pricing it to sell, but until it does it will just be hanging out with my other pretenders.  If you have any questions, please ask!

Grand Maximus - Transformers Wiki (tfwiki.net)
Grand Maximus (グランドマキシマス Gurando Makishimasu) is the younger brother of Autobot Supreme Commander Fortress Maximus. He was among the Autobot refugees who fled Cybertron four million years ago under the leadership of his brother, and like his sibling, became a Headmaster when they crash-landed on the planet Master. Grand Maximus's mental functions are contained in his smallest component, Gran (グラン Guran), who connects to a larger Transtector named Grand (グランド Gurando) to boost his strength to normal Transformer levels. Just like his bro, he pilots a Maximus battleship, which serves as a second transtector with which Grand combines to form "Grand Maximus". Though they seem virtually identical in all other respects, Grand Maximus is significantly smaller than his titanic elder brother, only a bit taller than God Ginrai in robot mode and with room for just a couple of human-scale rooms at most in his starship form.
