Product Numbering & Bar Code Verification of Phantom Plarail Sets

Impossible.
The 4th generation EF-58 box was found, it is G-26 (1977). This proves the Plarail Musuem and the us as the entire team wrong that the 4th generation Densha Box was manufactured from 1978-1980. It was actually from 1977-1980, or could be 1977-1979! Most of the Densha Box is G-27 (1978), but this EF-58 is much different than what we expected to be.
