There is no single "Alexandrian manuscript". Rather, there is a family of ancient New Testament manuscripts that are grouped together under the "Alexandrian" name. These manuscripts represent the oldest ones that have been found so far, and are considered by Catholic and Protestant scholars to be the closest to the original autographs written by the apostles. In contrast, the Eastern Orthodox church follows a "Byzantine manuscript" tradition represented by the vast majority of all manuscripts, though on average these were copied centuries after the ones represented by the Alexandrian family. The most accurate Greek edition of the Alexandrian manuscript tradition is the Nestle-Aland 27th edition. The most accurate English translation is The Comprehensive New Testament.

A tiny papyrus fragment of the Gospel of John is currently the oldest known "manuscript" of the New Testament. This manuscript (P52, also known as the John Rylands Fragment) has generally been dated to ca. A.D. 125. Today it is physically located at the John Rylands Library in Manchester, England. It contains the verses John 18:31-33, 37-38. It's an important document because it proves that the Gospel of John was written earlier than some scholars had thought (as late as A.D. 200). The fragment was found in Africa, near the Nile River.
