- DANFS entry 'Redpoll' (full text): 'A small finch found in North America, Europe, and Asia. The male usually has a red or rosy crown and streaked back and sides. Redpoll was laid down as YMS-294, 10 June 1943 by Associated Shipbuilders, Lake Union, Seattle, Wash.; launched 11 August 1943; sponsored by Miss Joanne Swanson; and commissioned 11 September 1943. In the Puget Sound area through the fall of 1943, YMS-294 moved south to San Pedro in January 1944 and operated out of that port until April. On the 21st, the motor minesweeper steamed west and arrived at Pearl Harbor on 1 May. Thence, she completed a run to Midway and back and in June she continued on to the Marshalls. There through the end of the war, she engaged in patrol operations, convoy escort duty and minesweeping operations, principally out of Kwajalein and Eniwetok. In December 1945, she returned to Hawaii; remained there until February; then, ordered inactivated, got underway for the east coast. She arrived at Charleston in late June, received new orders, and in September retraced her route back to the Gulf of Mexico for duty in the 8th Naval District. On 12 November she was decommissioned and placed in service at New Orleans. The following month she assumed Naval Reserve training duties at Houston. Named Redpoll and redesignated AMS-57, 1 September 1947, she was recommissioned effective 20 November 1950, but until 1952 remained in the 8th Naval District as a reserve training ship. In May 1952, she departed Lake Charles, La., and steamed back to the Atlantic coast. Assigned to the 5th Naval District for the next 5 years, she operated out of Norfolk for 2, then, in June 1954, shifted to Yorktown for duty with the Mine Warfare School. On 7 February 1955, Redpoll was redesignated MSCO-57 and in October 1957 she was ordered to Chattanooga for reserve training duty. She arrived at her new homeport 2 November and 6 days later, 8 November, was again decommissioned and placed in service. A little over 1-1/2 years later she completed her last tour. She was placed out of service and struck from the Navy list 1 July 1959.' DANFS spec line: 'YMS-294: displacement 270; length 136'; beam 24'6"; draft 8'; speed 15 knots; complement 32; armament 1 3", 2 20mm., 2 depth charge projectors; class YMS-1.'

- Authoritative Navy source establishing identity, construction (builder, launch, sponsorship, commissioning), the wartime San Pedro/Pearl/Midway/Marshall Islands narrative, the 1945-1946 inactivation transit and 8th Naval District reserve-duty sequence, the 1947-09-01 naming/reclassification, the 1950 recommissioning, 5th Naval District and Mine Warfare School service, the 1955-02-07 MSC(O) redesignation, the 1957 Chattanooga transfer, and the 1959-07-01 strike. Contains no asbestos, insulation, or materials information whatsoever - supports no asbestos claim. The narrative uses the name 'Redpoll' anachronistically for the pre-1947 YMS-294 period. The decommissioning sentence ('On 12 November she was decommissioned') carries no year; narrative order implies 1946 - NavSource/uboat.net print 1945, variance carried in gaps.

- Post-Navy research career documented in institutional primary records: after conversion this hull served 1960-1976 as R/V Sir Horace Lamb, a Navy-owned vessel operated by Columbia University's Geophysical Field Station (the Bermuda SOFAR station) under Office of Naval Research sponsorship. Lamont Geological Observatory Technical Report no. 7 (CU-7-69, October 1969, Ants T. Piip, 'Sound speeds and temperatures of Bermuda waters in autumn and winter: October 1964-March 1966') states 'All stations in this report were taken from our R/V SIR HORACE LAMB' and was 'Submitted to Acoustic Programs, Office of Naval Research under Contract Nonr 266(65).' Technical Report no. 4 (CU-4-67, 1967, Piip, 'The sound channel in the Bermuda-Barbados region: April-July, 1964') documents 'detailed, consecutive precision sound velocity profiles ... obtained at each station on cruise 106 of our R/V SIR HORACE LAMB,' performed 'under the aegis of Acoustics Programs, Code U68, U.S. Office of Naval Research.' The Smithsonian Institution Archives holds a Sir Horace Lamb cruise-data item (cruise of 1968-06-26 to 1968-06-29) among its oceanographic cruise records.

- Institutional primary records establishing that this specific hull (the former YMS-294/AMS-57) operated as Columbia's R/V Sir Horace Lamb on ONR-sponsored acoustic research out of Bermuda through the 1960s-1970s - confirms the ship's continued existence and working career 16+ years beyond Navy service, a period in which original-era materials could have persisted aboard. The reports document operations, not materials: no asbestos, insulation, conversion-yard, or demolition information. The conversion (1960) and disposal (1976) events that would have disturbed era materials are not documented in these sources.

- Finding
- NARA deck-log coverage for this hull is cataloged in two places. Special List 44 ('List of Logbooks of U.S. Navy Ships, Stations, and Miscellaneous Units, 1801-1947'), ship-number list, catalogs a single run of YMS-294 deck logs: 1944-01-15 to 1945-12-31 - covering the Marshall Islands operations period through war's end (the 1943 commissioning-to-year-end period is not in this run). Separately, NARA's 'Navy Deck Logs Available in the National Archives Catalog' page lists Redpoll (MSCO-57) - 'Commission: September 1943; Decommission: November 1946; Recommission: November 1950; Decommission: November 1957' - with digitized logbooks for 1956-01 through 1957-11 (e.g., the January 1956 logbook at catalog.archives.gov/id/218446597), i.e., the 5th Naval District / Mine Warfare School period through the final commissioned month. The NARA index's 'November 1946' decommission date corroborates the DANFS narrative chronology against NavSource's printed 1945.

- Catalog-level confirmation that deck logs for this hull exist in NARA custody (wartime run) and online (1956-1957 run) - not a retrieved record: log text was not pulled or reviewed. Deck logs record daily ship activity and would document operations and availabilities, not necessarily materials; retrieval is a lead, not a finding. The 1943-09-11-to-1944-01-14 commissioning-period logs are absent from the Special List 44 run - their custody status is undocumented here. Does not establish any asbestos fact.

- Finding
- Class-design documentation: the YMS-1 class comprised 561 wood-hulled auxiliary motor minesweepers built at 35 yacht yards to one design - 136 ft, ~270-320 tons, twin General Motors 8-268A diesel engines on two shafts - for coastal sweeping of acoustic and magnetic mines ('561 wooden-hulled minesweepers ... all of essentially the same design'; shipbuildinghistory's Mk. II designation for this hull is the single-stack variant, matching the 'YMS-135 subclass' naming used by secondary indexes - NavSource's class index confirms YMS-135 through 445 carried one stack). Because the class is wood-hulled and diesel-powered, the dominant WWII-era shipboard asbestos pathway (boiler and steam-line lagging insulation) does not apply to this design. Any asbestos aboard would be limited to era-typical small-craft applications (engine gaskets and packing, diesel exhaust insulation, electrical materials, winch/windlass brake linings); none of these is verified for the class or this hull.

- Secondary reference works, not a hull record: they establish the class design (wood hull, diesel plant, no boilers or steam system) but contain no asbestos or insulation-material statement for the class and none for this hull. The absence of the steam-lagging pathway is a design-level inference from the documented machinery type; residual era-typical applications are possibilities only and are not established as installed, present, or absent aboard this hull. Does not establish individual exposure or quantity.
