How many pins does it have in the circuit board?
Someone said it might be an encoder but I see "103" on it which is used on potentiometers to indicate 10k ohm (10 x 10^3)
It has 3 pins, and I found that it's a linear (B), 10k ohm (130, as you said), potentiometer. I found similar ones, but the 9 and 5 at the top concern me. The others that I found have a 60 and a 6 there instead.
Linear checks out for this kind of application.
Potentiometers are pretty basic things. About the only thing I can think of that would be specified electrically is value (10k), wattage rating (but I doubt much current is sent through these in this application), linear/logarithmic taper, tolerance (often 5%, or 10%) and maybe the type of contact/track or something (probably doesn't matter).
Those numbers could be manufactured date or lot codes or similar.
How does the thumb "wheel" attach? Or is it built in? I can't tell from the single pic.
Other things to consider are the pin spacing and physical dimensions.
