NOS Sugino spider for old school BMX bikes. Fits one piece cranks as well as some of the three piece cranks.
Standard Sugino size so it works with Sugino chainwheels and other 110 BCD chainwheels. This does not fit the Takagi chainwheels and you will need a Takagi spider for them which I think is 135 BCD.
This Sugino spider is NOS and never used or mounted.
