Actual Item is pictured. 

VACUUM VARIABLE CAPACITOR  10 -500 pF, 10 kV, 50A, 30 MHz,  KP1- 4

          Capacitor were made for Military equipment have a special stamp in the form оf a Rhombus.

          High quality made for the military equipment. Made in ex USSR 1974

             These CAPACITOR are used, dismantled from equipment.

    I did many photos. Please, look carefully. What you see is what you get. If you need additional pictures or some more information of these item please email & I will be happy to help.

Please feel free to email me if you have any question about these capacitors.                
Thanks for looking and GOOD LUCK!
P.S. Also I have other VACUUM CAPACITORs are  from 3pF to 1200pF. Please, look my other items. 
P.S. Also I have Mounting Brackets for VACUUM CAPACITORs. If you need Mounting Brackets, inform me. I will do lot for you. Thank you. 
NOTE: It should be borne in mind, that after long storage at the moment of supply on vacuum capacitors a complete nominal voltage, individual breakdowns can occur in them, which then disappear.
Such breakdowns are not dangerous for capacitors and have no influence to their future work at nominal voltage, but they can negatively affect operation of other elements of of equipment.
Therefore it is necessary to produce the supply voltage smoothly or by stages, and provide protection of elements of equipment from loads at the breakdowns in capacitors at the moment of inclusion.
So, before installing capacitors to the equipment is necessary to make their training. Checking (training) produce by gradually increasing voltage on the capacitors from zero to nominal value.
