Ah,, ok.. the original model didn;t have any panel lines at all.

If you are looking for reference imges, search for Polar Lights Jupiter II or Ron Gross's Jupiter II.

Ron did a scratchbuilt real world model J2 that was as accurate to the original moel as humanly possible. Then Polar Lights contacted them, and together, they produced a styrene plastic model kit based on Ron's input. it was released on both regular and Chromed versions. (I own both)

It even had a complete interior, even though there's no way a real world show interior would fit inside it.

Way too many people take way too many things way too seriously.
