4015 Active Playground Super Set
This link gave me a fairly blank page at Toysaurus Canada, but not to worry it's probably this Apple Safari browser I'm on!
That's probably the answer. On the other hand, all three of these sets (4015, 5130, 5964) appear in the building instructions area and the older sets do not appear in the archives yet. I think this is because Playmobil does not fully understand why collectors, and even just plain customers, want/need part and set information. 
I fully agree, Indianna.
The reason Geobra offer a spare parts service is to supply parts which children have lost or broken in their recently-purchased sets (this has been stated publicly). They only offer parts from sets from the last 5 or 6 years (I think that's right?). The fact that some parts can be used to fill gaps in much older sets, or satisfy adult collectors who are amassing armies of klickies or creating room-sized dioramas is mere serendipity, they do not (until perhaps very recently with a certain part having a 'crossroads' theme in its name) see collectors as a potential market.
That said, it is perhaps puzzling why they are bothering to devote bandwidth (and the time taken to create PDFs) to publishing online the building instructions of older sets. Perhaps they feel they want to offer a service to people who find their childhood Playmobil sets in the attic? What is the point of them helping someone to assemble, say, a 3666 castle using downloaded instructions, only for them to find a crucial part is missing and DS cannot supply it (this may not be a good example but I am sure there must be parts in 3666 which DS cannot supply)?
Don't get me wrong, I would like to see EVERY set of building instructions on the Playmobil websites (the number on there keeps going up -it's at 1448 now), but many sets (e.g. 215 out of 218 Specials) never had building instructions, so we do not know the part numbers in these sets, except by intelligent guesswork.
I think the "ersatzteile finden" feature (thanks for prompting me to go and have a look at that Indianna!) will only ever show parts currently available from German DS - itself a useful feature, but not ideal for finding the parts I need in other places.
I'd love to know what others think Geobra are doing by posting old building instructions, btw!
