Re: Horizon 2020
That was my experience with ESO ( non-Eu !)
4 telescopes requiring 4 identical auxiliary systems.
2 were built in Germany, one in Holland and one in Belgium - to three different designs - to match contributions.
IIRC one of the low country units never worked and we had to build another copy of the German ones out of slush fund
