Then there is no Patrician I or II, there are only the german Patrizier and Patrizier II.
Well, either you misunderstood or Wikipedia's got it wrong. Because The Patrician 1 and 2 are on GOG. And not only that, I have boxed, English-language copies of both.
As for instructions, I'm disappointed GOG doesn't have the manual for The Patrician in the package. I thought that manuals were pretty essential.
It's a pretty thick book, and quite interesting too as it contains a lot of extra information about the Hanseatic League (remember when manuals did that?). I can't help you find it online, but I'm here so I can answer questions if you have any.
