Comment by PhilMH:
I suspect that the reason for separating them is because the UK one below shows MCPS as the rights society, whereas this one shows STEMRA (Dutch society). However,
looking at the eight releases in Discogs with this barcode, I don't know that we can necessarily go by the rights society to determine the release market, because some of them showing the UK society MCPS were manufactured on the Continent, and others manufactured in the UK show STEMRA! All of them seem to show the German label code and the French distribution code on the back cover. It might be better to show them all under Europe, as any store ordering this from within UK and Europe would have been supplied by whichever PolyGram warehouse had stock; the linked Italian entry should remain separate, though, as it doesn't have the barcode, nor the 842 552-2 catalogue number, as it was distributed by Dischi Ricordi rather than PolyGram.
