Thanks for a wonderful line up and a trip down memory lane, Andrew.
I only had the Cowboys & Indians when I was a lad, from your collection, plus some knights and consttruction workers. My two favourite cowboys were one with white body/legs and red arms, and one with green body/legs and white arms. I think the pirates, soldiers etc. came after I was already too old to be given Playmobil for birthday and Christmas presents.
One thing I liked about the early sets were what they to the imagination like horses bridles and reins. They were not really necessary, but now they exist in modern sets of course you want them in.
What I hated were those cowboy hats that look the same back to front, because they had a toggle in the back that was supposed to line up with a notch in the figure's hair, but 99% of the time dug into the softer plastic, because you hadn't got it on quite straight or even back to front, and caused hair damage. Happily they soon realised the pointlessness of the toggles and notches and designed them out, but not before all my cowboys had really bad hat-hair.
