Q is for Quack, Quack-quack...Quack-quack-quack!

I call Ducks Quack-quacks, so this little lot had to be 'Q', only taken into the collection today, I was going to cop-out with something quadrupedal! I found them in a local charity shop (Shelter, if you're wondering), no price and I can't tell you what they cost as they had whatever was in my pocket as shrapnel, over four quid, because the shopkeeper counted the four and threw the rest in the counter tub for another charity!

The lot included a porcelain goose which might be Wade but is a bit small, and too well painted (for Wade) and a resin chick for a tit-bird (non-native so I can't give more, like a colourful long-tailed or grey-tit!) both of which have gone in the TBS (to be sorted) box, where they will be joined by these as soon as this is up. But I'd like to ID these if anyone has a clue.

All ducks, the large one (top right) is terracotta, hollow (slip-cast?) and not so needful for putting a name to, but the others aught to be identifiable, and are within the scope of the collection, being a clay or composition duck (bottom left) and a set (or part-set) of dark brown or black plastic ducks, not much bigger than 1:32, and usable with Britains farm figures.

I say part-set with a question mark as there are three pairs as far as mouldings go and two singles, I suspect there should be ten - 5 pairs. I thought they might be Marx, but they are unmarked, I'm assuming Hong Kong, and the sort of thing Marx would have sourced over there and sold on a card as an adult collectable for cabinets or mantle-shelves. Google is no help, nor is STS on this one, so if anybody knows these; let the rest of us know.

The composition duck also failed the STS search, being too small for Elastolin or the other obvious candidates, and as I say, I'm not sure what it's made out of, and with total paint coverage I can't do my usual exploratory scrape-test! Again; if you recognise it, please comment.
