That's an interesting design of swingset; not one I've seen before.

Unlike the bog-standard swingset in the US, which is typically all steel tube, that one looks like it has extruded (aluminum?) verticals and then a tubular horizontal weldment as the top piece. Further, the horizontal looks like it was hot-dip galvanized as a finished unit. The verticals were painted before assembly, not after, because of the bare-metal bolt heads. The fasteners are presumably stainless, since I don't see any rust marks below them. It's got an interesting bearing/bushing at the top of each chain, probably to make it not squeak; that strikes me as a fairly luxe feature.

I couldn't find any similar ones searching around online, although my Google searches don't turn up many European models at all (thanks, Google).

The photo doesn't go up enough to be sure, but it looks like the top bar is an unbroken one-piece section. That would make it pretty bulky and awkward to ship. (The vertical pieces look like they come apart into about 4 ft sections, which means they were likely palletized at one point. Maybe the extrusions are not done in the same place as the rest of the manufacturing..? That's certainly plausible.)

If someone recognized the design/model, I think that would probably be a significant clue towards the photo's location; at the very least, the manufacturer would probably have a fairly good idea of where they normally sell to.
