Hopefully to add to these explanations: here are the internals of a gas cap Gougler model I have. There are no reference points on the cap itself, so the combination begins by turning left to stop. Full combo is LS-R9-7-2.
It's not clear how the numbering on the labyrinth disk (205) corresponds to the final combination. The top bar is the locking mechanism in this model.


And my attempt at an "explanatory" image for my friends who have no idea what I'm excited about


Thank you all for your cutaways and videos!
