What are these lines?

In my previous post in this thread, I attached a stripped-down photo of ISS trail, which I assumed was out of focus (photographed stars immediately after, which were a bit out of focus).

On looking at the original shot, I noticed distinct lines in the streak (cropped section attached). I'd like some opinions on what these might be. Did I fluke good focus, with the lines relating to structure & orientation, or are they just some weird interference pattern relating to poor focus etc?

Did a quick web-search looking for similar obs, but turned up with zilch. Any ideas? Thanks -

Cheers -
