Sorry to say that I don't think any of it is made in Europe. From https://www.raspberrypi.com/news/meet-the-engineers-behind-r...:
Hardware engineers Simon Martin and Chris Martin have been beavering away on Raspberry Pi 500+ for years, through a process of iteration that’s seen a total of ten factory trips to China, six PCB revisions...
You're correct actually, I missed that. With Raspberry Pi they moved production to the UK (Wales) in 2012 - (Factory tour article in 2023 - https://www.jeffgeerling.com/blog/2023/how-raspberry-pis-are... ).
I wouldn't be surprised if they move production back to the UK assuming Pi 500+ starts doing well.
