Question about the G1 Powerdasher Jet type (Crona, I believe?) I've got one that's broken and I want to replace it. The body is BLACK (with silver arms and a red head and legs). But all the ones I'm seeing for sale right now have a BLUE body(still with silver arms and a red head and legs). So my question is... Which one was the version Hasbro was selling the US as a mail away, and which one was from Japan? Or is that even the difference? WHAT IS the difference, I guess?
