- Finding
- NARA holds this hull's complete crew muster rolls spanning 18 January 1943 (commissioning) through 31 October 1945 on microfilm Roll 6845, scanned under the NARA-Ancestry collaboration - the authoritative crew-roster record for the entire commissioned life of the ship.

- Limitations
- Coverage dates are the record's span, not ship-event dates: the batch manifest cites log coverage through 12/13/1945 while this catalog file unit ends 10/31/45 (discrepancy carried in gaps). Muster rolls establish who served aboard, not materials aboard; individual exposure cannot be inferred from presence. Page images are Ancestry-hosted (paywalled); names not enumerated this session.

- Finding type
- historical_record
- Finding
- Four cataloged war-diary file units cover this hull's first ten months (18 January-30 November 1943): the commissioning and shakedown/early-service narrative exists on microfilm but is not digitized; no war-diary units for December 1943-September 1944 were located in the catalog, leaving the pre-Leyte interval documented only by the two 1944 action reports.

- Finding type
- asbestos_application
- Finding
- Era/class inference: an SC-497-class wooden-hulled 110-foot chaser built 1942 with a two-engine diesel plant (GM 8-268A) and no steam system would have carried only the small-craft era-standard asbestos applications - engine exhaust lagging, gaskets, valve packing, and electrical insulation. The class was built 1941-44 (438 delivered), squarely inside the Navy's asbestos-use era, but wooden 110-footers lacked the boiler/steam-pipe insulation load that drives most ship-asbestos findings.

- Harbor Boat Building construction trades 1942; crew 1943-45 (complement 28)
- Limitations
- Inference from class, build era, and propulsion type only - no ship-specific documentation establishes that any of these materials aboard this hull contained asbestos, and none establishes that they did not. Does not address crew-era exposure, quantity, or legal eligibility.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the hull was scrapped in 1955 and pre-disposal material condition is undocumented. CourtListener coverage is partial: 1 of 4 base queries completed (SC-726 opinions - 2,390 tokenized hits, all collisions, no ship references in the returned page); three base queries plus the authorized asbestos variant were blocked by fleet pacing (sl-08). Does not establish that asbestos is or is not present; does not establish or defeat any claim of exposure or legal eligibility.
