You can use a Q meter to measure the Co of an inductor so I suppose
you can do the same for a transformer. You look at the capacitance
needed to achieve resonance at two frequencies then use some maths
to figure out the extra C.  You can also measure leakage inductance
and parralel inducatance of a transformer.

H.P. sell one that goes to 70 MHz or so. They can be had for about $4K
on the commercial surplus market. The Marconi TF1275 is better but
is older and may be more difficult to find.
