1) I dig the Susan B. quote!!

2) Sorry I didn't see the beginning of this thread, but if we're talking NR/SR/GS spindles for double cranks, just to clarify, the length added due to CPSC regs. was 2.5 mm (1.5mm drive side, 1.0mm non-drive side).

English & French up to mid-1977 (68-SS-120) = 112 mm long Italian up to mid-1977 (70-SS-120) = 113mm long English & French thereafter (68-SS) = 114.5 mm long Italian thereafter (70-SS) = 115.5 mm long

Triples were of course longer....

The difference between the frames' BBs is usually (but not always) as you stated (68 E/F vs. 70 Italian).

Cheers and how's the V12 doing?

Yes, it's a spindle, but y'all can call it an axle if you'd prefer....
