Hi HelenCan I just ask when you say 'tree swing' do you mean the one which is num 162 in der katalogue IV p329?
Also where were they produced, from the 'spiel' on the box, I'd guess Germany?
I don't have the Katalog handy at the moment but I am guessing it's the one you think it is...it's the pencil holder one. I have the box for the smurf one but I bought the Kwak one in a lot with other smurfs and only recently found out that one variation is actually the Kwak one.....actually I think the one with the green paint around the bottom is actually the smurf one and the other with just the brown is the Kwak one (will fix the above post where I got them back to front).
From what I hear...the Swing on the Trapeze version on p329 of the Katalog is not an official item and is from people combining both the Trapeze super and the swing from the Tree Swing pencil holder.
I will check out the Spiel box tonight to let you know what they say...I am pretty sure they are all Germany CE markings from memory but will get back to you.
I also forgot that I had the Kwak Hammock as well which is pretty much the same except for a different shade....I got it without the Hammock cloth bit but I am guessing the cloth is probably the same as the smurf one anyway.
