David,
Your 1941 schematic matches the one I have, at least in the area of interest around the band-switch. That is an interesting thought about disabling one of the ranges. The cap in there at the moment is certainly post-war, but may have been added to replace one that was of a value different from spec.
There has been a lot of work beneath the chassis on this set, apparently on several occasions in it's history, and with varied levels of attention to detail and accuracy. I reasoned that the best option was to clean it up throughout, and get things back to trustworthy values - this is not an untouched piece where originality can be preserved, but it should be a nice performer.
For the 5600 pf, I'm leaning towards finding a silver mica cap (can't really go wrong) but could try a film cap until parts arrive.

I don't hold with furniture that talks.
