Well, what do you know, a search for "origami by Aso Reiko" brought up several books of childrens models, looks like they are in Japanese, and one of them has a pic of this model on the cover. I also found a page under this URL:
https://www.origami-resource-center.com/3-piece-spinning-top.html which is a short article by Kathy Knapp, who says: The fold is a variation by Reiko Aso of the Blooming Flower by Taichiro Hasegawa. The blooming flower becomes a spinning top when inserted into a windmill base. ..... from Chila Caldera /// -----------------------------------
