- Limitations
- DANFS documents identity, dates, custody, and disposal - not materials or asbestos content; the entry carries no specifications block (complement, dimensions unverified by DANFS). Mirror transcription cited because the live NHHC page returns 404. DANFS reads sold 10 December 1946; NavSource reads 12 December 1946 - carried in gaps.

- Finding type
- asbestos_application
- Finding
- Era/yard inference: an Evarts-class destroyer escort built 1943 at a U.S. Navy yard would have carried era-standard asbestos applications appropriate to a diesel-electric ship - exhaust insulation, gaskets and packing, electrical insulation, brake linings, and deck coverings - but no boilers or steam lagging; builder Boston Navy Yard (Boston Naval Shipyard) is documented as a tier-3 asbestos-era yard in the Atlas dataset.

- Limitations
- Class/era and builder-yard inference only - NOT a hull-specific finding. The GMT diesel-electric plant means the largest asbestos categories of steam ships (boiler and steam-line insulation) do not apply; does not quantify material or establish any individual's exposure.

[6]In re John Crane, Inc., No. 01-03-00698-CV (Tex. App. 1st Dist. 2003) - worker alleged exposure to John Crane gaskets and sealing materials at Boston Naval Shipyard (Atlas shipyards.json, yard record 'boston-naval-shipyard') [court_record]

- Finding
- Builder-yard asbestos context: the Atlas shipyard record for Boston Naval Shipyard carries a verified litigation product-identification finding - a worker alleged exposure to John Crane gaskets and sealing materials at the yard - and a 1943 peak employment of 50,128. DE-274 was built at this yard May-September 1943.

RN-service maintenance records for HMS Gardiner would be at UK National Archives (ADM series), not surveyed.

- Finding
- No qualifying ship-specific asbestos record located for DE-274: no hull ACM survey, no abatement or hazmat disclosure (hull scrapped June 1947 - no preservation record exists), and no qualifying asbestos case names the vessel. CourtListener sweep complete: 'HMS Gardiner' returned zero opinion hits; 'USS O'Toole' returned zero opinion hits; 'DE-274' returned 21 hits that are all identifier collisions (customs-court entry numbers, docket-entry strings, OCR splits - none vessel-related); 'Gardiner asbestos ship' returned 20 hits that are all surname/place collisions; 'O'Toole asbestos' returned 70 opinion and 196 docket hits that are all plaintiff/entity surname collisions (none vessel-related).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard at construction - era materials could have been installed; does not establish or defeat any claim of exposure or legal eligibility. Docket sweep reviewed first page only (20 of 196 hits) - all surname collisions; vessel names do not appear in case captions, so caption-level review is sufficient classification.
