Since no one found me a pic for my question in
>>6247800 I found something interesting.
One detail in the hasbro renders that made the takara one different was the cannons on the hasbro version had a black spot of detail painted in, takara's did not, but this image is from the 2017 australia hobby and toy fair, also sporting takara's lack of painted detail.
Supposedly of the 2 trypticons present, one was pre-production, this means takara's one from the magazine scans is either incomplete itself or the hasbro one's prototype was derived from takara's first, or some other more sensible theory that I'm just missing, either way hasbro trypticon sporting takara's deco in australia.
