If you switch to a Stronglight, Magistroni, or Agrati, you will most likely need a greater diameter spindle.

.

C1232 is double version of C1200, 54-mid 60s.
C1200 was Williams top model, 170mm only, 116 BCD so min 36 cog but it looks good too.

.
Stronglight apparently did metric and BSC versions - possibly marked with "A" for Anglais (not Acier).
If a Stronglight is 9/16" pedal thread then it's 3/8" spindle.

I'll check out Magistroni and Agrati.
