RGC-83 GM Cannon II from Gundam 0083 Stardust Memory made into a 1/144 High Grade model kit. Sadly I have no recollection as to this mecha ever coming out in the OVA. Its either I wasn't watching it really well or this mobile suit's appearance was just a flash of frame but notable & worthy enough for the toy engineers at Bandai to merit its own rendition into plastic forum.
In my personal opinion, the most notable quick appearance but made into a toy was the VE-1 Elint Seeker from Macross: Do You Remember Love Movie. If you saw the movie, it was just a few seconds of air time of this very unique but beautiful VF-1 Valkyrie variant.
The 1/144 HGUC RGC-83 GM Cannon II is selling for $$$ at Amazon, 1020 yen at Amiami, 1120 yen at HobbyLink Japan, 1190 yen at Hobby Search
Construction Manual and Color Guide for the 1/144 HGUC GM Cannon II was translated to English from the Japanese manual posted at Dalong's Gunpla Review site.
