Wow, lots of helpful answers!
Part 7 is from the 3716 farm.
Yes, of course! I have that farm, too!
If is surplus to your requirements, maybe we could come to some sort of trade as another one would be useful to me.
You are welcome to it, send me a PM! The corners where it hinges are broken off though!
Isn't 8 legs to a cot?

Yes, of course, silly me!
There were several #25 on the boxes I messed with. And #29 reminds me of the polar tent, but I think it's not exactly that...
25 could be the front forks for a bicycle maybe?
Some on the second picture remind me of the 80's space theme, I also have some of those but can't place them, too early after a long work holiday.
Can't see them on Playmospace pictures, but you may be right, Rasputin.
8 is from one of the frames/legs for tables 30-21-7420
4 looks like a truckbed side or rear hinge. But cannot find it....it's familiar though...
31 and 14 are Lego. 31=flag
Thanks for the link, PlayMoto. 4 could be off a truck, I will think about that. I am sure you are right that 31 and 14 are Lego, the lack of the usual 'Lego' logo puzzled me!
From this angle, #6 looks like a matrass that pulls out from under a sofa. Only weird thing, I've never seen it in that colour.
PlaymoDB shows it in dark blue, for instance: Part Number: 30 22 0350. Sets 3966 and 4062 have it.
Does it have an oval shaped dent in it, on the other side?
Spot on Birdie! The mold number even matches the red one I have. (No oval indentation on either one, though). Its from 3230
