I once resurrected an RBL receiver, and a dozen mica capacitors and only 
one oil-paper capacitor failed. I just checked the instruction book, and 
it says "Capacitor, Molded Mica."  Some are suspiciously large for mica, 
1000 to 8000 mmfd, so they could have been paper.  Maybe quality control 
was lax during WWII, but I have been suspicious of micas ever since.
