John,

My notes include this from Bob Camp <bob@cq.nu>:

"The material in the IF slugs is different than the material in the RF
slugs so don't mix and match. "

This would imply that what you report above is right.

(The R-390 non-A is a different matter altogether.  It has slugs of both 
different diameters and different materials, and may even have slugs 
selected for best tracking in each transformer.)
