"to reason" (for and) "against reading"...

[A MM]

I've just begun re-reading L.L.L.
Also begun feeling my way around here.

Have some comments which maybe I can get some responses for.

To begin with, should the spelling remain "labour" and not be chnaged to "labor" in a new reading?

The "our" spelling will not match the way the word is spelt in the newspaper.

AE and BE are variants of the same language and do not (yet) require translation one from the other. If I were quoting an AE text, I would retain the AE spelling. Conversely, BE spellings should be retained by AE quoters.
A translation from one language to another obviously demands substitution. eg the German for "Sonnet" is "Sonett".
I find the apostrophe in "Labour's" annoying, however. It was probably a printer's error and has been retained ever since.
