Stronglight Super Competition Mod. 57 Cranks Set 1950s Alex Singer Herse

  
Used Stronglight Super Competition mod. 170mm arms, French pedal 14mm threaded. The original left crank arm will accept a pedal, but I'm not confident how well it will old it under pressure of riding up a hill during an Eroica kind of ride. The replacement left arm has Marque in the logo, unlike the original, but has the similar milling as original, not like the later blockier crank arms. I cleaned the crank arm extractor threads with the proper VAR tool, so they are excellent.
