I googled 'euromig professional 150' and got nothing, I found that elmag link afterwards but looking at those pics it's not the right people anyway.
That looks quite an old machine but that might not be a bad thing if it's in good working order. Older machines were often built using better components.
Think the new Euromig is By Javac, chinese made imported into Belgium the one you have is a older model not chinese not sure where from could be from erfi in Germany
