- DANFS record for this hull: 'PC-1124 (q.v.) was renamed Chocura (IX-206) 20 February 1945.' The entry notes the name is a variant spelling for Mount Chocorua, New Hampshire, and that this was the second Navy vessel of the name (the first a Civil War gunboat). No separate NHHC DANFS entry for PC-1124 exists - both candidate URLs return 404.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates cross-check against NHHC DANFS, the official chronology, and uboat.net, but it publishes no decommissioning or striking date for this hull. Contains no asbestos content. The dry-dock photograph documents a repair availability at Manus after battle damage but identifies no yard facility or work scope.

- DANFS Severn IV entry, Leyte Gulf paragraph
- Finding type
- vessel_history
- Finding
- DANFS names this hull in a third-ship narrative: at San Pedro Bay, Leyte Gulf, the water carrier Severn (AO-61) supplied 7th Fleet units through daily air attacks; 'on the 24th [November 1944], an enemy plane penetrated the CAP cover and released a bomb aimed at the water carrier. The bomb missed Severn, but hit PC-1124 then receiving water.' PC-1124 was alongside Severn taking on fresh water when the single attacking aircraft's bomb struck her.

A deck log is not an asbestos record in any case.

- asbestos_application
- Finding
- A steel-hulled diesel-driven submarine chaser built in 1942-43 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a vessel of this type and period were machinery and diesel-exhaust lagging, thermal and acoustic insulation, gaskets, valve packing, electrical insulation, and deck coverings, installed within a small, confined hull volume. As a diesel-driven vessel she carried no boilers or steam turbines - the boiler/turbine lagging pathway of steam ships does not apply, but the small-ship confined-space exposure dynamic applies with full force.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming PC-1124 or Chocura (IX-206) was found in the public sources searched. The hull was sunk off Manus in October 1945, pre-dating modern ACM-handling regulation and survey practice - no abatement-era paper trail exists to find. CAVEAT: CourtListener could not be queried this session - the fleet helper reported the daily quota exhausted (~3.8 h to reset); logged as blocked in search_ledger, not as a negative result. The only 'asbestos aboard' material surfaced is law-firm marketing content (freeasbestostesting.com lists 'USS Chocura (IX-206)' in a generic auxiliary-ships page) asserting asbestos without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era inference for a 1942-43 combat vessel is reasonable but not ship-proven, and the litigation repository search is a genuine open gap (throttled, not run). Deck logs (NARA, per Special List 44) and any Manus drydock work orders are undigitized or unverified leads. Does not establish or defeat any claim of exposure or legal eligibility.
