    I'm going to take a guess and say it's a 100k potentiometer? If so what is the adjustment range on it? I can't find any specs or links.. the clear turn part says "HDK" but that's all.

    While it is hard to tell from the incredibly tiny images posted yes this is indeed a 100K pot from the 104.

    You can adjust it between zero and 100K. You get about 3/4 turn to cover that range.

    when in doubt bust the multimeter out.
    Then count the number of turns it takes for full scale.

    Place your ohmeter across the two outside pins to read the pot value. Place meter from center pin to either outside pin to see if value changes when screw turned.
