According to new Plarail museum, the predecessor of ちょうとっきゅうひかりごうNO.1 was predicted to be でんどうちょうとっきゅうひかりごうセットNO.1, however its existence was not confirmed.
The existence of the predecessor is found by me today. It was quite hard to find because the set name was not indexed in Google search engine.
You can see that the でんどうちょうとっきゅうひかりごうセットNO.1 is a circle layout, but ちょうとっきゅうひかりごうNO.1 is a oval loyout.
