I have the inductance and ohms of a few inductors, if you want that info. I have an N30 gold text from a 1994 limited edition V847G, a Wilson Effects halo, a Dunlop yellow, and a couple black inductors from the 90's. I measured them with my EXTECH LCR meter.
As for measuring and logging your pots. If you can build a fixture to spin two or more pots at the same time, you can do the following.
You can use the Innovate Motorsports SSI4 to data log and/or view up to four pots in real-time. The SSI4 requires 12V to power it, and it has a 5V output you can use to power a linear pot. I wouldn't use its 5V power output for both pots because it would parallel them, so you'll need another regulated 5V supply for the other pot. The 12V supply, and the 5V supply share the same common ground. Likewise, the additional 5V supply must also share the same common ground, so the two pots will accurately reference the same ground. Basically, tie the negative of everything together.
It is designed for Automotive data logging, but you can use it for this purpose. Check the manual, but you can probably power it with a 9V battery, or a 9V adapter.
Anyway, the SSI4 has four 0-5V inputs. You connect the wiper and the negative lug of the linear pot to input 1, and the wiper and the negative lug of the second pot to the second input.
In the LogWorks software, each channel will have its gauge. So pot 1 will have its voltage displayed, and pot 2 will have its voltage displayed.
Use the voltage at the min extreme, and the max extreme for each pot, that is being displayed on the screen to set the 0% and 100% parameters for each pot, and give them a name. Linear for the linear pot, and Hot Potz 1 (etc...) for the other.
If the actual readings end up being something different at each extreme of the pot's rotation than 0V and 5V, and they probably will, like 0.00V, and 5.2V, then 0.0V would = 0%, and 5.2V would = 100%.
You input that info into the fields, and the software updates that gauge for you. You have to do this for each pot, turning each pot to its extremes to get the voltage for each pot, to set the parameters for its gauge.
It has been about 15 years since I did this, but this is how I remember it working. I did this for sensor data on an ATV to tune it. For example, the TPS was at 1.12V at 0% throttle, and the wide open throttle (WOT) was something like 4.65V. So I inputed 1.12V = 0%, and 4.65V = 100%. I called the gauge TPS with those parameters, and it worked excellent.
With this, you'll be able to compare the wah pot against the linear pot based on percentage. I think you can also plot gauges/channels against each other to compare the sweep of the pots on a graph.
You will know if you are turning them accuratly if they all start at 0% together, and end at 100% together. They'll all be different within that, but they should begin at 0%, and end at 100% at the same time.
Do you have plans on having a pot manufactured? If so, I hate high torque pots. I want the wah to move quickly, and freely. Inductors make their impact, but, IMO, the pot is the most critical part of the sound, and its feel shouldn't get in the way. Leave that to the axle/hinge pin tensioner.
By the way, what are some 100k pots that actually have the correct Icar taper?
