I looked through your other thread and didn’t see, but it woukd be helpful to post a pic of the crank to make sure everyone is on the same page. 1st gen C Record, Victory, Triomphe double cranks use symmetric 109 mm spindles in English and Italian BB. At some point after that they went to 111. If you’re using earlier gen cranks, then you dip into the morass of asymmetry and variable lengths.
