One can try to measure the capacitance with an analog bridge like a Heathkit IT-11 Capacitor Checker. Lift one wire of each coil so only the capacitor is in the bridge measurement. The bridge does not place any high voltage so there would be no arcing. Use short leads well separated and deduct about 5pf for stray.
