It's also worth noting that the margin planks weren't unique to the soft patch area- you see them around features that break up the deck plank pattern such as hatches, vents, turrets, etc.. You can see them around the deck-edge bits in Jeff's photo as well. They are some more examples and information (Royal Navy but relevant)
