Also the YouTube channel: https://www.youtube.com/channel/UC4TnW1n...dQDNKWvZCA has covered some research topics for the Panorama Express sets.

Back to main topic, introducing:

パノラマとっきゅうふえふきはっしゃセット

Panorama Express replaced Shindai Express for unknown reasons. You can see that the initial lighter cream colour Shindai Express was printed in the box art, so this Panorama Express should have been in it's final stages of production as seen in the type of drive wheel. I have covered another set "パノラマとっきゅう基本Ｎo.３セット" in the past, where the Panorama Express replaced L Limited Express. In the contents list on the box cover, Shindai Express and L Limited Express respectively was printed, not Panorama Express. I have that set, so I'm able to confirm it's existence.

A view from our team: The seller intentionally replaced the vehicle.

There is no solid evidence, but it's existence is confirmed. So another active case is on.
