Hey, good afternoon! I found my fish paper on Amazon. Here's the link to what I bought: Fish Paper

Essentially, fish paper is specially made to resist current and should not burn or smolder.

For your second IF can, there's one fixed capacitor and three trimmer caps. I don't have measurements for the trimmer caps, but that fixed cap is a 300 pF mica. 

By the way, I gave the forum an updated schematic for the 46-480, to publish to the Philco Library's "Service Info" documents page. Here's a link, if it may help you: Schematic 
I formatted it for 11" x 17" paper, so it's much easier for most folks to get printed. I can print these at Office Depot for $0.35 a sheet.
