First, it would seem that the last "real" m1911 chambered in 22lr was made in 1945. Good luck affording one.

Second, somebody has something backwards, either the Wiki article you posted or this one. According to this article, Umarex owns Walther outright, so Umarex are both manufacturer and importer, but if being made by Walther qualifies it as "real", then yours was a real as you're going to find.
