- Official DANFS record for this hull: Lapwing-class minesweeper (dp. 950; l. 187'10"; b. 35'6"; dr. 9'9"; s. 14 k.; cpl. 78; a. 2 x 3"; cl. Lapwing). Launched 21 December 1918 by Todd Shipyard Corp., New York City; sponsored by Miss M. Sperrin; commissioned 9 April 1919, Lt.(jg) J. Williams in command; reclassified ASR-3 on 12 September 1929. Service: sailed Boston 23 May 1919 for Kirkwall, Orkney Islands, arriving 5 July to clear the North Sea minefields; returned via Lisbon, the Azores, and Bermuda to New York 19 November 1919; for the next 11 years operated along the east coast and to Cuba and Puerto Rico on salvage, target towing, mine recovery, experimental underwater radio tests, net laying and tending, and tending submarines; October 1930 sailed from New London with Submarine Division 4 for Pearl Harbor as submarine tender until 5 January 1931, then Coco Solo, Canal Zone, until August 1933; decommissioned at Pearl Harbor 21 August 1933, remaining there until April 1937 when her berth changed to Mare Island Navy Yard. Recommissioned 12 November 1940; sailed San Diego 3 February 1941; reached New London 10 May 1941 - her base for the remainder of active service. WWII duties: training divers, submarine search and rescue exercises, station ship, and target ship for submarine torpedoes; operations to Halifax, Argentia (Newfoundland), and several times to Key West. Decommissioned at Brooklyn 4 February 1947; used as a target and sunk off New London 31 July 1947.

King's 1923 grade is listed as 'CAPT' - likely a rank-at-later-date convention; flagged in gaps. No strike date given.

- asbestos_application
- Finding
- Era/design inference: this hull is a 1918-19-built steel Lapwing-class minesweeper with a full steam plant - two boilers and a triple-expansion engine, unlike the diesel-electric WWII minesweepers - so its insulation load was that of a steam vessel, not a diesel one. Machinery and construction materials of the WWI era were commonly asbestos-containing: boiler casing and fireroom insulation, steam-line lagging, valve and flange gaskets, machinery packing, compartment and joiner insulation, and brake linings. Documented disturbance-phase events for this hull: 1918-19 construction at Tebo Yacht Basin, Brooklyn; Sep-Nov 1929 submarine-rescue-vessel fitting at the Boston Navy Yard; Oct 1930-Aug 1933 Pearl Harbor/Coco Solo tender service; layup at Pearl Harbor (Aug 1933-Apr 1937) and Mare Island Navy Yard (Apr 1937-Nov 1940); 12 Nov 1940 recommissioning at Mare Island; WWII rescue/training duty out of New London (1941-47); Feb 1947 decommissioning at the New York Navy Yard (Brooklyn); Jul 1947 torpedo-target sinking.

- Limitations
- Inference from documented design, machinery type, construction era, and documented activities - NOT a hull materials record. No survey, specification, or material schedule naming Minesweeper No. 39/AM-39/ASR-3 was located; establishes no asbestos content, quantity, location, condition, or individual exposure. The Sep-Nov 1929 Boston Navy Yard fitting is documented as an event but its material scope is undocumented; era practice makes asbestos use plausible, not proven. Does not establish or defeat any claim.

The litigation negative finding is incomplete because the CourtListener index itself was unreachable this session; 'Chewink' is a low-collision name (a towhee finch) but the AMCU-19 same-name hull (ex-LCI(L)-701) and the ASR-3/ARS-3 designation collision remain possible confusion sources.

- Sources differ on secondary points, all flagged: (a) first decommissioning - DANFS 'decommissioned at Pearl Harbor 21 August 1933' vs shipscribe 'out of commission 21 Sep 33'; DANFS is carried (both agree on the Pearl Harbor event and the 1933 year). (b) Spec blocks differ across configuration: DANFS as-built minesweeper (950 dp., b. 35'6", dr. 9'9", cpl. 78, a. 2x3") vs NavSource ASR-3 configuration (1,400 t., l. 188'7", b. 36'8", dr. 13'2", cpl. 91, 1x3"/50 DP; 1942: 2x3"/23) - a real configuration difference from the 1929 submarine-rescue conversion and wartime fits, not an error, but NavSource does not label it as post-conversion. (c) Strike date - shipscribe disposition table reads 10 Jun 47; DANFS and NavSource omit a strike date entirely; carried from shipscribe with sourcing noted. (d) Sinking agent - DANFS 'used as a target and sunk off New London 31 July 1947'; shipscribe adds 'by a Mark 28 warshot torpedo from USS CORSAIR (SS-435)'; NavSource reads 'sunk as a target 31 July 1947' - consistent on date/event; the Corsair/Mark-28 detail rests on shipscribe alone.

- Limitations
- Record-group mapping only - no box-level retrieval performed; existence of asbestos-specific documents for AM-39/ASR-3 is unknown until surveyed in person. Muster rolls, deck logs, and action reports are personnel/operations records, not materials documentation. Nothing in this row is an asbestos finding.
