Changing Inductance

You could try to "guesstimate" the number of turns by multiplying the number visible on the outer layer by the number of layers.
You then remove 5% of that quantity. Won't be very accurate, but anyway, a change of 10% for such a coil is rather cosmetic.
Some cheap techniques to measure inductors have been described in the ZLCR thread, here:

I will try your suggestion. I read somewhere that in crossover parts 5% tolerance is
acceptable. If 10% is also OK then I do not have to change the 10mH. I can use it
in place of 9mH which I am doing at present and wanted to try with the correct
value.

Thanks for the interesting ZLCR thread.
