Thank you, everyone. Those are amazing answers & amazing knowledge y'inz came up with so quickly. That was pretty astounding!
Leefert especially wins the "What is This?" prize.
I was also extremely happy to see that a lot of what I thought wasn't Playmobil actually was, & glad I didn't throw away the things I doubted were. In the lot was also an Indian canoe which I was sure wasn't PM but I eventually found a "geobra" on it.
This is the last of the unidentified stuff from my original purchase from the retro toy store. I've been really wrong so far, but I think maybe possibly most of this may be PM?
Would anyone like a go at proving me right or wrong?
