Note: Capacitors new, after long storage in  warehousehas capacitors have cosmetic defects! Paint in some places has peeling from long-term storage. Also brass screws may have slight oxidation. (See photo!)
Capacitors were produced in 1988-1989. These capacitors are no longer made. 
Real condition look at the photo!!!
1Lot = 3 Capacitors!!! 

Capacitors  have a special stamp Quality Mark (quality control) .
