Sorry I don't know how to make the pictures smaller.
These are from spares I collect over the years.
The first two pictures are of the 1K rotors
The third picture is the bottom of the 5K rotor- see the R5 in the circle.
The forth picture is the top of the 5K rotor
The fifth picture confirms the resistance of 5K
The sixth picture is the box of one of the 5K rotors came,The box on the left is the 1K box.
