Are you  certain that the core material was not powdered iron?
 
Yup. I was surprised, but it's Neosid F14 material, suitable for tuned  
circuits up to about 4 or 5MHz. The loading was cylinders about 1.5 inches long  
and 1 inch diameter: there are 8 of these inside a coil of about 5 inches  
diameter, so they're pretty loosely coupled.
 
As is so often the case these days, the demand for cores for RF tuning  coils 
has diminished, and Neosid do very little in the way of 'classic'  components 
now...
