- Study period
- 1903-1937
- Limitations
- The NPS search-indexed row was readable, but the NPS-hosted PDF returned an HTML access page to local automated retrieval. The table does not explain the interval between 1903 launch and 1911 commissioned-column entry, give a decommissioning date, or document fate after the 1937 sale. It contains no asbestos finding.

- Study period
- 1933 records; 1940 schedule
- Limitations
- The schedule describes records proposed for disposition, not the records' content or present survival. The 1933 date supports a hull-specific records trail within the service era; it does not establish operations on any particular day, equipment materials, asbestos, or exposure.

- 1902-1936 catalog range
- Limitations
- The public finding aid describes the file, not its contents; the file was not retrieved. The NHHC page was indexed but returned an access error on direct retrieval. The 1902-1936 range is catalog coverage, not independently verified active service or an asbestos finding.

- Finding type
- historical_record

- Search on 2026-09-24
- Limitations
- This is a bounded negative search result, not proof that Pentucket had no asbestos. The underlying NHHC history, 1933 drawings/logs, and any surviving material records were not examined. CourtListener authentication was available but shared pacing prevented completion of the required litigation sweep at drafting time; its result must not be treated as a negative case search.
