[APML] Royal Gold and Supra films

[Alan Voetsch <critter12952@yahoo.com>]

Chris, Michael and all,

I don't think I've forwarded the response I got from
Kodak earlier this month. When this thread was being
discussed last month, I did summarize this reply.
Anyway here it is in its entirety. Now I'll see if I
can find the post that tells how to tell new from old
RG films. :-)
