Gunport lids while "active service" changed quite a bit :-)
1765 until 1783 sides paid with rosin, the lids too, some lower ones partially black, where they meet the black gunwhales
1787 to 1797 sides painted yellow ochre, the lids too, some lower ones partially black, where they meet the black gunwhales
1803 to 1814 forst painted yello ochre, the lids too, some lower ones patially black, where they meet the black gunwhales (or alternatively the yellow lines repositioned to follow the ports), later on before Sept. 1805 the lids were painted black (and alternatively the yellow lines repositioned to follow the ports) to suit Nelsons personal taste.
After 1816 - 1920 black and white with Nelson checkers.
1920 to 2016 - yellow ochre the lids painted black.
2016 to ??? - pink ochre and the lids painted black.
So pick one ;-)
