Do you have a transistor?

The easiest way to get the inductance is to put it in an oscillator circuit like the colpitts oscillator in picrel, and choose component values in the audible range and listen to it, comparing against known inductor values.

This is the way some LC meters work, except they use a frequency counter and the “range” switch is used for swapping out different capacitor values in the oscillator.

For the other values (like how much current it can take/wire gauge, core saturation, q, etc.) it’s a little more complicated but obviously we’ve got the most important one covered.
