Unimat DB200 or SL-1000 Idler Intermediate Pulley (DB / SL, DB 35 or DB102-7), fits the Motor Bracket that  connects between both the headstock pulley and electric motor to change and adjust the speed of the live spindle.  Was lightly used on an Unimat SL-1000.  

All parts are very clean and have been well maintained. The pulley appears darker than it is because of the lighting.

The camera flash creates the copper color showing in the listing, no rust. Please review the photos since they are part of the description. Contact me with any questions prior to purchasing. Thank you for your interests.
