Hi Yonna
I just checked the ones that I have and I don't have any markings on the actual swing however the swing from the playground is longer.
As gar as markings go I have Germany Schleich S for the Tree Stump and Made in China (with & without a blue paint dot) on the smurf. I have another Tree Stump coming so I will check to see if there are any differences.
Here's my page from the website on the Tree Stump variations if you're interested in more info:

I hope that helps
