New Shooting Star Gordon & Stream Lined & Steam Thomas

Interesting thought, so I looked up the new Oigawa James to see what chassis type it used because it is a smaller model but couldn't find that info. I assume it is the same as the Oigawa Thomas because it to is smaller. Although I can't see exactly the motor configuration I will guess its the same as the original but with the battery entry from the bottom....

I'm curious about that too since the real Oigawa James is a C56 and I had presumed Tomy simply used a modified version of their exsisting C56.
