The first three die-cast toys by Nostalgic Heroes are Side Machine (RG-01), Kikaider (RG-02), and Hakaider (RG-03). The side car of the Side Machine can be separated from the bike by removing two small screws.  I was impressed with the toys' construction quality and paint job. However none of the three toys comes with any accessory. Furthermore, they do not have any operational part--even the gun on Hakider’s hand is not removable. The lack of any functionality certainly limits their playability, especially when comparing with most of the vintage die-casts.
