Like I said, I could be wrong. Anyone know for sure?

Yes, those lines are laminations glue lines, not tree rings.

My Ted Hendrickson prop is also made of thin laminations and is, I
have always thought, quite beautiful. Ted retired several years ago.

Lastly, as a Long EZ builder, owner, and flyer whose experience with
EZs dates back to the early Rutan days, my response to the scenario
and images depicted can be summed up in two words, Holy ****!
