You got me wondering, so I did some web "research" on rice paper capacitors and found this on another forum, link to follow:
"Some quality paper condensers are still safe to use, most notably the Stromberg Carlson, Westere Electric manufactured units which were used by, among other firms, the Radio Corporation,, but, and is is a most important caveat, the only units which are truly safe are those made with imported fish and rice papers. This material spiked in price after June 17th, 1930, at which time the new Hawley-Smoot act placed a 600% tarriff on insulating papers. Condensers made after the autumn of 1930 are, I'm afraid, not to be trusted. "
It's not my information and I have no idea if it's accurate, but it's certainly interesting enough to post.
