Class spec block differs from NavSource hull figures (98 t./20 kts./22 complement vs. 148 t./21 kts./28) - standard vs. full-load and wartime-fit variation; carried as a gap. No asbestos content.

- Finding
- Construction roster entry: 'SC 690 | Annapolis YY | Annapolis MD | 148 LDT | 110 LOA | 16-Dec-42 | To Free French 1944 as CH 106.' Lists the hull directly as SC-type (110-foot) pennant 690 built by Annapolis Yacht Yard, delivered/commissioned 16 December 1942, disposed to Free French forces 1944 as CH-106. Corroborates the SC-497 hull type independent of the PC-690 commissioning designation.

- Finding type
- asbestos_application
- Finding
- A diesel-powered, wooden-hulled submarine chaser built in 1942 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel combatant of this type and period were diesel-exhaust lagging, machinery-space thermal insulation, gaskets, valve and pump packing, and electrical insulation. As a diesel vessel with no steam plant, the boiler/turbine lagging pathway of steam ships does not apply; the confined-volume small-craft dynamic - machinery spaces feet from berthing - applies instead.

- Limitations

Names era-standard applications, not confirmed installed materials. No quantity. Wooden-hull construction reduces but does not eliminate the insulation/gasket pathway. Product names are normalized era terms; no manufacturer attribution.

[10]Designation cross-check: NavSource designation line ('Commissioned PC-690, 16 December 1942; Reclassified SC-690 in April 1943'); shipbuildinghistory SC roster (lists hull as SC-type 690 from delivery); HyperWar SC-497 class roster [other_primary]

- Finding
- CORRECTION: this hull carried a PC-series designation at commissioning (PC-690, December 1942 - April 1943) but was never a PC-461-class patrol craft. PC-461-class vessels were 173-foot steel-hulled craft; this hull was a 110-foot wooden SC-497-class subchaser throughout, and the Navy corrected the series prefix to SC-690 in April 1943. Records grouping her with PC-461-class 'submarine chasers' would misstate her construction type entirely.

- Limitations
- Corrects a designation/series artifact, not a material claim. The April 1943 reclassification date is NavSource's; the mechanism (SC-hull construction contracted under PC-series numbers) is consistent with the documented wartime SC/PC program but the contract-level detail was not separately sourced this session.

- Finding type

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming SC-690 / PC-690 was found in the public sources searched (see search_ledger). For a 1942-built wooden chaser transferred to France in 1944, no abatement paper trail is expected - the hull left U.S. custody before asbestos regulation existed. CourtListener partial: 'SC-690' opinion search returned 2,911 hits and 'SC-690' docket search 26,405 hits - ALL top-20 page hits are court docket-number collisions (e.g., Kentucky Supreme Court 'No. 96-SC-690-MR', Alabama 'SC 690'), no qualifying asbestos case naming the hull; 'PC-690' base queries could not be completed - fleet-wide pacing sustained ~2.5 h this session (helper exit 2), logged as blocked, not a negative result.

- Absence of a located public record does not prove absence of asbestos aboard - era inference remains reasonable. Litigation search is partial: SC-690 queries completed but are pure-collision strings (court docket numbers); PC-690 queries and asbestos-qualified variants remain an open gap (blocked by sustained fleet pacing). The NARA deck-log and war-diary file units (unexamined contents) are the open primary-source lead. Does not establish or defeat any claim of exposure or legal eligibility.
