Fortunately I had a NOS Stronglight BB with a Swiss fixed cup and a 120mm spindle. Also figured out the reason for 118mm vs 120mm wide Stronglight spindles... The 120mm spindles were for bikes with 126mm wide dropouts. They correct the chain line for 6 speed FWs! 118mm spindles were for 120mm wide dropouts...

Beautiful, that was my first bike in the exact same color. Would love to have come across that.

French Hub/Dropout Width Standards
So Chas, based on this info: my 1972 PX10 has a 118mm Stronglight spindle, and 123mm dropouts, but I am having them spread to 126mm. Should I be replacing my BB with a 120mm spindle? Glad I caught this info!
Front - 96mm OLN (Over Lock Nut)
Rear - 122mm OLN (5 speed)
118mm -120mm = 2mm = 0.079" or about 5/64" (less than 1/8")
Hold your fingers 1/8" apart and look between them!
In general. that is an insignificant amount but... a 120mm wide spindle may be a better choice, not because of any chain line hoodoo but because as crank arms are removed and re-seated, they fit further onto the spindle.
I put this Flickr album together one night about 10 years ago when I was building up a SS beater. It needs to be updated but check out the photos and click on any that look interesting. Scroll down to read my notes below the pictures.

One last point, when you have the rear triangle spread make sure the offset is equal side to side and most importantly the dropouts are parallel up and down, front to rear. Any ham fisted hammer smith can spread the dropouts but can they make sure the frame is properly aligned???

My PSN10 is my beater with a healthy rattle can layer to protect against the elements. I continue to be thrilled with the ride quality of the Super Vitus frame.
