Observed registry history
History here means states and change events observed by Grizzly Bulls in validated FAA registry snapshots. Observation windows are not legal ownership periods and do not establish the exact time a real-world change occurred.
“Observed from” and “observed through” are FAA snapshot retrieval boundaries, not legal ownership dates. A source effective date appears only when the API supplies one. Historical registrant names, addresses, aliases, and other personal details are not displayed here. Current FAA withholding remains authoritative over retained history.
