I’m very curious about the deck construction. If you don’t mind putting my curiosity to rest: What are the regular lateral lines which interrupt the rotary abrasive-disc trails?
They almost look like butt welds, or pressed stiffening ribs, but neither seems particularly plausible.
Grasping at other not very convincing possibilities: Print-through from underdeck deck beam welds? Hard to interpret from the photo …
Lovely photo, top-looking workmanship…
