I think it's necessary to keep in mind that most (with a few exceptions) tube data sheets show "typical" operating values, not maximums. When I look at other schematics and most spec charts, I see "typical" of 40uF in the specs, but many schematics with more than 40uF, and I have seen and replaced some of these myself, usually with 47uF caps. Keeping in mind that these sets have operated for several decades like this, it is my opinion that this 40 vs 50 is a tempest in a teapot and unworthy of much debate. I believe the schematics are correct as drawn and are not errors, and I personally will continue to NOT second guess the engineers who designed the radios in the first place.

For yourselves ..... ??? ..... do as you wish.
