Sansin (aka Sunshine, Sanshin) was the hub manufacturer. Sakae Ringyo (SR) was also a Maeda partner. Sakae also made cranksets under the Suntour name.
+1 on searching for Sugino chainrings, since they made the Superbe cranks for Suntour.
I have a Sugino Aero Mighty with 144mm BCD. Great crank, but 42t is a PITA, correction, the knees.
