- Finding
- The official index entry reads 'AMc196-199 Now APc7-10' - documenting in a Navy publication that the hull ordered as coastal minesweeper AMc-197 (CNO directive of 19 Jan 42 for AMc 150-199; this unit contracted 29 Apr 42) was completed and commissioned as the small coastal transport APc-8. One hull, two designations; never a second hull and never commissioned as AMc-197.

- Finding
- Volunteer-compiled service record: commissioned USS APc-8, 3 Apr 1943, LT. Leo E. Hansen, USNR, in command; a 12-officer command roster running to 31 Jul 1946; ribbons American Campaign Medal and World War II Victory Medal; 'assigned to the Asiatic-Pacific Theater'; decommissioned 31 Jul 1946 at Naval Station Long Beach; struck 8 Oct 1946; transferred to MARAD 1947; sold 19 Feb 1948 to Foss Tug and Launch Co., Seattle. Carries U.S. Navy Yard Charleston photo #765-43 (9 Apr 1943) showing APc-8 on the blocks in Dry Dock #2 among eight craft - a documented post-commissioning yard availability six days after commissioning. Page annotates 'There is no DANFS history record for USS APc-8.'

- Population
- Twelve commanding officers Apr 1943 - Jul 1946 (NavSource roster)
- Limitations
- Volunteer-maintained archive, not an official repository; 'Asiatic-Pacific Theater' is boilerplate repeated across all APc pages and the ribbon block (American Campaign + WWII Victory only, no Asiatic-Pacific Campaign Medal) does not corroborate a specific station. Launch date (4 Oct 42) and decommission date (31 Jul 46) conflict with the official record - official figures carried. The drydock photo is the strongest item; the authoritative original is Navy Yard Charleston photo 765-43.

- Finding
- No qualifying asbestos record located for this hull or class: no asbestos survey, abatement record, owner hazmat disclosure, shipyard work package, or docketed case naming APc-8 or AMc-197 was found in the sources searched (see search_ledger). No class-level asbestos itemization exists for the APc-1 wooden-hulled diesel transport type in the inspected record. CourtListener returned zero exact-name hits and only name-collision hits on hull-designation tokens ('APC' professional-corporation suffix; 'A.M.C.' American Maritime Cases reporter).

- Limitations
- Absence of a located record does not prove absence of asbestos aboard - era-typical components on a 1942 diesel craft (gaskets, exhaust lagging, packing, brake/clutch linings, electrical insulation) cannot be ruled out, and the documented April 1943 Charleston Navy Yard drydock availability is an unexamined maintenance event for materials. Does not establish or defeat any claim of exposure or legal eligibility.
