- NavSource documents identity, milestones, service narrative, and published specifications - it contains no materials or asbestos information and does not address exposure. NavSource's official-primary-source status is not established; it is used as a ship-specific compilation and archival lead. The page's spec block lists a single 40mm bow gun; secondary compilations (HyperWar ships list) list a 3"/50 dual-purpose bow gun - the discrepancy is carried in gaps rather than resolved.

[9]Era inference built on: NavSource specifications block (all-diesel GM plant, welded construction per NPS nomination); NPS NRHP 15000716 (machinery-space layout, all-welded steel hull); GAO HRD-80-2 (Navy asbestos-use era, see ev-09) [other_primary]

- Finding type
- asbestos_application
- Finding
- A welded-steel amphibious gunboat built August-September 1944 inside the Navy's documented asbestos-use era: era-standard applications aboard a small diesel warship of this type and period were thermal insulation in machinery spaces and exhaust runs, gaskets and valve packing in fuel/lube/fresh-water systems, electrical insulation, and fireproofing/firefighting textiles - in a hull ~158 ft long where 71 men worked in confined spaces. The all-diesel plant (two quad packs of GM 6051-series-71 engines) means no steam plant aboard - the boiler/steam-line lagging pathway of steam vessels does not apply; the diesel confined-space dynamic (machinery spaces, exhaust lagging, gaskets, packing) is the relevant pathway.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1944-built Navy vessel of this era is a reasonable era-consistent inference for asbestos-containing insulation, gaskets and packing, but that is not ship-proven. CourtListener coverage is the exact designation strings at opinion and docket level; variant spellings (LCSL-13, LCS(L)-13) and the Japanese name (Oniyuri) were not exhaustively searched - one variant opinion search was attempted and stood down by fleet pacing, logged in the ledger. Does not establish or defeat any claim of exposure or legal eligibility.
