>>9063658Subtle variation due to limited technology is a key part of Showa Rider design and appeal. Its obviously impossible for a figure to capture all the intricacies, so going hodge podge is kind of expected. The comparatively fat proportions is another issue but then again we also can't have OG figuarts skinny or 2000's Bandai era muscle lad in the mix. Its a hard aesthetic to really nail down.
All things considered it kinda makes sense for a hodge podge looking figure to bare the colors of what modern suit makers consider to be a nice all-encompassing look for Rider 1.
And yes, production description specifically says its based on the current suit.
