Takara Microman: Magne Power Giant Acroyear

I bought this set out of curiosity almost a decade ago in a nearby mall (Ali Mall, so named because Muhammad Ali supposedly is a part owner). Yes, it's not in good shape, and I regret that fact. If anyone can contact me in the comments about how to clean this properly, I would be very grateful.

This Takara Microman set is composed of three smaller units that combines into a larger unit. After some research, I think it's called the Magnemo Acroyear. The whole Magnemo line can supposedly gattai with each other.

EDIT:
The kind folks over at the Micronauts/Microman FB page have been kind enough to point me to a source for more information about this toy - apparently known as the 055 Giant Acroyear from the Magne Power Series.

This seems to be the "main robot," and closely resembles the classic Acroyears. The arrow-like missile on the right hand is a pressure click system. When the toy was new, this was definitely an eye hazard.
