   Limitations

   NavSource is a volunteer-compiled secondary source, not an official record; used for specifications, dates, and disposition, corroborated by uboat.net and the NARA muster rolls. Documents no asbestos information. 'Fate unknown' conflicts slightly with uboat.net's 'sold to be broken up for scrap in late 1948' - carried together in the record.

   PC-612 crew, 1943-1946 (rosters: ~65 wartime complement, 49 aboard Oct 1945)

   Limitations

   Primary personnel record - documents stations via personnel-transfer entries, not a complete cruise log: mid-1944 and several report months have blank sailing fields, so continuous positions are not proven. Navy #115 was the wartime FPO designation used for NOB Guantanamo Bay (philatelic record; NHHC distribution lists confirm an 'NOB, Navy #115' addressee). The lone Western Sea Frontier (Treasure Island) sender is ambiguous - a cross-country transfer and a Pacific posting are both possible; Pacific service is NOT established by this record. Personnel rosters, not a materials record: contains no asbestos information.

   asbestos_application

   Finding

   A diesel-driven patrol craft built 1942-43 sits inside the Navy's documented asbestos-use era (substitution of alternative insulation did not begin until the early 1970s - GAO HRD-80-2). Era-standard applications aboard a vessel of this type and period: exhaust-system lagging on the two H-O-R diesel mains, machinery and engine gaskets, valve packing, bulkhead insulation, deck coverings, and electrical cable insulation - all within a confined 173-foot hull. Carrying no steam plant, the boiler/turbine-lagging pathway of steam vessels does not apply.

   Limitations

   Class/era inference only - no hull-specific insulation survey, material list, or work package located for PC-612. Names era-standard applications, not confirmed installed materials; no quantity; no manufacturer attribution. The absence of a steam plant makes the asbestos inference materially weaker for this hull than for steam vessels of the era.

   Limitations

   Secondary profile, not an official record, and it does not assign the Pacific service specifically to PC-612: Bogigian's prior ship, USS Stevenson (DD-645), was a Pacific-theater destroyer, so the Pacific element may attach to Stevenson rather than this hull. The hull's own muster rolls document a uniformly Caribbean/Gulf career - Pacific service for PC-612 is unresolved (carried in gaps). No asbestos information.

The CourtListener opinion index returned 0 results for 'USS PC-612'; the docket index and hull-number queries were blocked all session by fleet pacing and remain unsearched. A live-web sweep for 'PC-612' + asbestos returned only part-number and municipal-code collisions. Law-firm listicle content asserting asbestos aboard Gibbs-built or PC-class vessels was excluded by source policy (no primary sourcing).

    Limitations

    Absence of a located public record does not prove absence of asbestos aboard - and the litigation sweep is incomplete (opinion index clean; docket index unqueried this session, see sl-07/08/09). The hull's 1948 sale to a private buyer means no museum/abatement record chain exists; her war diary (RG 38) and deck logs, which would resolve the Pacific question and any yard availabilities, are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
