Sorry about the delay in posting. It is a hand-made gadget by certain Japanese enthusiast (owner of this bike). Frame was made by Toei, but, this nice (or weird) crankset was not made by Toei. From the description of this photograph, 36 spokes are 1.2mm dia, chainrings are Simplex 51 and 45, crank fixing bolts are remodeled parts from TA crank puller.
I heard that he is a professional mechanician. He can do brazing and welding (include aluminum). In this bike, he created and remodeled some parts (brake cable hangers, yokes, head light mount, handlebars, seatpost and some other parts). I am not familiar with him. but, I heard that he is a nice guy.
