GBC laminator speed control pot ohms rating?

I need to replace the speed control potentiometer on my GBC Pro-Tech F60+ laminator, and I'm having a hard time determining the proper ohms rating for the replacement. The GBC part number is 220-161.

I thought pots generally had their ohms rating stamped on them, but this one has only A6021 9950. (See photo.) Can someone smarter than me interpret this? Or is this only a part number?

is the potentiometer open?

generally, the wiper gets burned, but you can still read resistance with n ohm meter

netsol, I'm reading 4.76 at the 20k setting, so that means it's a 5k ohm pot?

I sprayed it with some contact cleaner and it's working much better now. But the wiper is definitely darker than the ends. Does that mean it's wearing out?
