The current lead gives the account dated anchors—1951, 2005, 1973, 1974—that can be checked directly. The linked authority record independently contributes the date 1951-03-02.

Editorial analysis

Why this record matters

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
