- Finding
- NavSource record for this hull: PC-461-class submarine chaser; laid down 9 December 1942 by the Nashville Bridge Co., Nashville, TN; launched 15 March 1943; commissioned 12 September 1943; decommissioned 1 April 1947 at Subic Bay, Philippines; struck from the Naval Register 23 April 1946 (as printed - see limitations); transferred to the State Department, Foreign Liquidation Commission 27 August 1947 and sold to Negros Navigation Co. of San Francisco, CA; fate unknown. Spec block: 295 t. light / 450 t. full; 173'8" x 23' x 10'10"; 22 kts; complement 65; armament one 3"/50 DP, one 40mm, two 20mm, four K-gun depth-charge projectors, two depth-charge tracks, two rocket launchers; two GM 16-278A diesels (serials 14209 & 14210), Farrel-Birmingham single-reduction gear, two shafts. Call sign NCUM. Eight-officer CO list 1943-47 (LCDR Keeling through LTJG Daniels). Photo record includes PC-1243 anchored alongside PC-1139 at Chichi Jima, Bonin Islands, fall 1945.

- Limitations
- Volunteer secondary compilation, not a primary registry - milestones and specs are consistent with uboat.net and NavalCoverMuseum where they overlap, but are not independently verified against the Naval Vessel Register (NVR detail pages sit behind a navy.mil login wall this session; NVR also excludes pre-1987 disposals). The printed stricken date (23 April 1946) precedes the printed decommissioning (1 April 1947) and the final CO's January-April 1947 tenure - internally inconsistent, see gaps. 'Negros Navigation Co. of San Francisco, CA' is as printed; the documented Negros Navigation Co. was Bacolod-based - attribution unverified. The '2,880bhp' per-engine rating is the combined figure mislabeled (sister pages print 1,440 bhp). No asbestos or material content. Photo establishes anchorage presence at Chichi Jima, not operations.

(Nashville, Tennessee); ordered 27 February 1942; laid down 9 December 1942; launched 15 March 1943; commissioned 12 September 1943; 'History: Stricken on 23 April 1946'. Commanding officers listed for the WWII window: James Robert Keeling USNR (12 Sep 1943 - 15 Mar 1944), George Haines Weed USNR (15 Mar - 4 Jul 1944), John Berne Hannum 3rd USNR (4 Jul 1944 - 14 Feb 1945), George Eugene Quincy Johnson Jr. USNR (14 Feb - 18 Nov 1945).

- Volunteer secondary compilation; sole source for the 27 February 1942 order date (carried as secondary). Repeats the '23 April 1946' stricken date - likely derived from the same upstream compilation as NavSource, so not independent corroboration; the 1946 year conflicts with NavSource's own 1947 decommissioning (see gaps). No asbestos content; no wartime events listed for this hull.

- Finding
- Postal artifacts for this hull: (1) a cover postmarked 10 June 1943 at New Orleans, LA (USPO slogan machine cancel 'BUY / WAR SAVINGS / BONDS AND STAMPS', Official Business category) - places the fitting-out hull or her crew at New Orleans three months before commissioning, consistent with the Nashville-to-New Orleans delivery route of Cumberland River-built PCs (sister PC-1244 commissioned at New Orleans 5 October 1943); (2) a censored 'sailors mail' cover postmarked 17 May 1945 (Locy Type 7z, 'Censored and Free') - documents wartime correspondence from this hull. The museum's designation-history page mirrors the NavSource milestone set (laid down 9 Dec 1942 [page prints 'December 9 1943', a typographical slip - launched 15 Mar 1943]; commissioned 12 Sep 1943 - decommissioned 1 Apr 1947; struck 23 Apr 1946; FLC transfer 27 Aug 1947; sold to Negros Navigation Co.).

- Covers are physical artifacts with postal markings - genuine ship-specific documentation of presence/correspondence, but a postmark does not establish the hull's location on that date (mail could be posted ashore or carried); the New Orleans cover is consistent with, not proof of, the undocumented commissioning location. The museum's milestone table is derived, not independent (it mirrors NavSource including the 1946 stricken year and the 'December 9 1943' typo for keel-laying). No asbestos content.

[5]Negros Navigation Co. published company history (experiencenegros.com PDF) - early postwar fleet: PT boat Princess of Negros (1947); two PC-type steel-hulled vessels acquired August 1947; third PC-type vessel acquired May 1950 [other_primary]

- negros-navigation-history.pdf, 'Post-war operations' section - August 1947 PC-type acquisition paragraph and May 1950 Florentina paragraph
- Finding type
- historical_record
- Finding
- The buyer's own history documents that 'in August 1947, two PC-type steel-hulled vessels were acquired and fitted with passenger-cargo (PC) specifications. The PT boat was sold and the two vessels were named Princess of Cebu (later to become the third Princess of Negros) and Princess of Panay,' with 'a third PC-type vessel which was christened the M/V Florentina' acquired about May 1950 and placed on the Iloilo-Bacolod route. Ex-PC-1243 was transferred to the FLC 27 August 1947 and sold to this same buyer (NavSource), so she plausibly entered the fleet as one of the August 1947 pair.

- Philippine inter-island merchant crews and passengers (Iloilo-Bacolod / Iloilo-Pulupandan routes, 1947-onward)
- Limitations
- The company history does not record ex-USN hull numbers - the identification of PC-1243 with either Princess of Cebu or Princess of Panay is plausible but unassigned and unverified. NavSource states 'fate unknown' for this hull. The 'PC-type' phrasing in the source is generic; the August 1947 timing and buyer identity match the FLC disposal. This is context for the documented sale, not a hull-specific finding. No asbestos content; a 1947-48 merchant conversion would be undocumented as to material condition.

- Finding type
- asbestos_application
- Finding
- A steel-hulled patrol craft built in 1942-43 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel combatant of this period were thermal insulation on machinery and exhaust systems, gaskets and valve packing, electrical insulation, and joiner/bulkhead insulation in accommodation spaces. As a diesel-driven vessel she carried no boiler plant - the boiler/turbine lagging pathway of steam combatants does not apply, but confined-space machinery insulation in a 173-foot hull remains the exposure-relevant pathway.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, work package, or construction specification was located for PC-1243. Names era-standard applications, not confirmed installed materials. No quantity, no manufacturer attribution for this hull. Nashville Bridge was an inland river yard building PCs under wartime contract; no asbestos-specific yard record surfaced for it.

- Finding type
- historical_record
- Finding
- CORRECTION: shipbuildinghistory.com's Nashville Bridge construction table gives PC-1243's disposition as 'Sold 1947 as Gosse, Mar Jan 1959' - but that merchant chain belongs to a different hull. NavSource documents that ex-PC-1222 (built by Penn-Jersey Shipbuilding, Camden NJ - not a Nashville hull at all) was sold 22 June 1947 to Lucienne Benitez Rexach of San Pedro de Macoris, Dominican Republic, converted to the luxury yacht Gosse, renamed Mar Jan on sale in 1959 to John Kallimbios of Maracaibo, Venezuela, and resold 1967 to George Simmonuti. The Wikipedia PC-461-class article independently documents Gosse as ex-PC-1222. PC-1243's documented disposition is instead the FLC sale to Negros Navigation (ev-01, ev-04).

- Corrects a secondary-source conflation, not a material claim. shipbuildinghistory.com is otherwise a reliable yard-record compilation (its table also supplies the Nashville Bridge builder context and the 14-hull PC build count) - the error is specific to this row's fate column. The correction is verified against two mutually consistent sources (NavSource PC-1222; Wikipedia class article). No asbestos content.

- No qualifying ship-specific asbestos record located: no insulation survey, abatement contract, hazmat disclosure, or litigation naming USS PC-1243 was found in the sources searched. The hull's own documentary trail is thin (milestones, CO list, two postal covers, one anchorage photo) - consistent with a numbered patrol craft with no published DANFS history. CourtListener was searched this session through the authenticated helper (four base queries): 'USS PC-1243' opinions and dockets returned zero; 'PC-1243' opinions returned zero; 'PC-1243' dockets returned five hits, all name collisions on inspection - Gates v. Eutectic Castolin (E.D. Wis., employment discrimination), Collins v. Energizer Holdings (W.D. Wis., employment discrimination), Woods v. Acapora (S.D.N.Y., contract/fraud), Lee v. Multi-Color Corp.

- Absence of a located public record does not prove absence of asbestos aboard. The hull's war diary and deck logs (RG 24, NARA College Park) are undigitized leads; the 1947-48 merchant conversion and any subsequent Philippine-flag documentation are untraced. Does not establish or defeat any claim of exposure or legal eligibility.
