Watch your step! 11th May 2023 Chris Jessop This is (or rather was) a tread from a ship’s boarding ladder; the wood is teak.You can see how much use it had: that’s a hard wood, but the middle is noticeably worn.I really hope that the tread was replaced BEFORE the rope holes at the left end gave;if not a sailor or a pilot could have had a very unpleasant moment,or even worse.
