It's interesting you say that, Tim. All of these cars were hand made so no two are identical. When studying restored examples, you can clearly see asymmetric traits in grille openings, headlight to fender angles, and various other small inconsistencies on the same car. Seeing how time was critical on making these, it's not surprising to see these errors.
Since time isn't critical on my build, those inconsistencies will be from me not knowing what I'm doing versus production volume!
