- Inventory listing only: the deck-log pages were not reviewed. The coverage window is not asserted as the commissioning or decommissioning interval and does not itself establish asbestos content or exposure.

[4]Batch-9135 source review: NARA Special List #44; NavSource YMS-55 page and YMS class index; CourtListener helper attempt and search_ledger [other_primary]

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public sources reviewed: no asbestos survey, abatement contract, hazmat disclosure, material schedule, or product identification naming YMS-55 was found. The NARA deck-log inventory establishes an archival lead but not asbestos content. The required CourtListener sweep was interrupted by the authenticated fleet pacing limiter before results were returned, so this row does not claim a litigation negative.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard. It does not establish or defeat exposure, causation, legal eligibility, or present-day material condition. CourtListener coverage is incomplete and is disclosed separately.

- Class narrative/specification block and YMS-55 propulsion block
- Finding type
- asbestos_application
- Finding
- The YMS type was a WWII-era wooden auxiliary motor minesweeper with diesel propulsion. Era context supports only a cautious possibility of asbestos-containing marine applications such as exhaust lagging, machinery insulation, gaskets, packing, or electrical insulation; no source reviewed confirms any of those products aboard YMS-55.

- Limitations
- Class/era context is not a ship-specific finding. The cited source does not state that YMS-55 contained asbestos or identify any asbestos product; no quantity, location, condition, disturbance, exposure, or causation is established.

- Limitations
- NavSource is a volunteer photo/archive compilation rather than a Navy registry. It supplies the hull-specific timeline used here, but does not provide an underlying Navy document image and contains no asbestos information. U.S. commissioning and decommissioning dates were not located.
