Can Pot Be Fixed/Cleaned

[TinCanAlley]

Does anyone know if the volume pot is linear or logarithmic on 70s Zenith sets? I cleaned this pot and tested it with my DMM and if I turn it slowly from start position, it starts at 40 and works its way down at a steady pace until it reaches around 20 and then it speeds up until it hits around 9 and slows back down. It does the same in the reverse direction. Since I have the set apart, I can't put it back in and test it in real time.

I read that audio pots can be linear or logarithmic and there is usually and "A" or "B" on it to note which, but this pot has no such marking.

It's the 63-10263 and is 40K.
