- Air Class Cutters page, Air Mallard list and generic characteristics; W-numbers table, WAVR 437 row
- Finding type
- vessel_history
- Finding
- The Coast Guard's Air Class Cutters history identifies Air Mallard among the transferred Air-class cutters; the official Coast Guard W-numbers table identifies Air Mallard (WAVR-437) as ex-SC-772. The Coast Guard Air-class page gives generic class characteristics including twin screws and a 16-person crew.

- Post-1945 transfer
- Population
- Coast Guard Air-class crews; Air Mallard assignment after 1945 transfer
- Limitations
- The Air-class page is class-level for characteristics; it does not document that every listed characteristic remained aboard Air Mallard or establish asbestos content. The hull-to-WAVR-437 identity is supported by the official W-numbers table, not by inference.

[7]Authoritative-source and public-record search ledger for USS SC-772 [other_primary]
- Locator
- search_ledger rows sl-uss-sc-772-sc772-01 through -09
- Finding type
- asbestos_application
- Finding
- No qualifying public ship-specific asbestos record was located in the authoritative sources searched: no asbestos survey, abatement record, product identification, hazmat disclosure, or qualifying adjudicated or pleading-stage asbestos record naming USS SC-772. CourtListener base queries could not be completed because the authenticated fleet pacing helper reported the shared request budget momentarily spent before results were returned; this is a search gap, not a negative CourtListener result.

- Limitations
- This is a bounded negative finding from the documented searches, not proof that asbestos was absent. CourtListener remains incomplete because the helper did not execute the requested searches. Secondary sources and law-firm/marketing pages were excluded under source policy.
