most of the time final assembly is the "made" mark... which is why some sets are marked made in china/spain/czech republic ... etc even though the vast majority of all parts for PM (the number I have is 95%) are made in germany and malta
Malta is as last I heard the exclusive producer of PM figures... first smile sets... and PM 123. Most if not all prepacked items... think take-along and advent calendars are marked made in the czech republic because that is where they are assembled and packaged.
Malta for all figures and Czech Republic for the advent calendar and take-along houses I know for sure... and I suspect that the sets marked China are primarily because the electronic elements are made there and the sets that come assembled like the new school bus and US exclusive pirate ship 5950 would be labor intensive to pack as the "ready to go" level they are boxed with for Mass Market... it would also appear that some of these similar but non-electric items undergo the same treatment in Spain.
