- Finding
- The National Archives Catalog inventories a digitized deck-log file unit for YMS-69 covering 28 August 1942 - 30 September 1944, spanning the hull's entire US Navy service from shortly after completion through the day of transfer to France.

- Archival description verified live in the NARA catalog; the 126 page images were not OCR-reviewed this session. Catalog title coverage (8/28/42-9/30/44) differs from the batch assignment's stated inventory window (1/1/1943-9/30/1944) - the catalog title governs the file-unit span. Deck logs document navigation and operations, not asbestos; no exposure claim is made from them.

- The NARA catalog inventories monthly USS YMS-69 war diaries spanning August 1943 through August 1944 and an action report covering Italy-area operations for the period '1/21-30' (catalog title states /43; the document is dated 2/1/1944) - establishing continuous operational reporting in the Mediterranean theater through the hull's last ten months of US service.

- Verbatim catalog titles only; report and diary page images not extracted. The Italy action-report title's '43' vs the document's 2/1/1944 date is internally inconsistent (a January 1944 reporting period would coincide with the Anzio period) - the inconsistency is disclosed, not resolved. No asbestos content.

- Finding
- YMS-69 was a YMS-1-class auxiliary motor minesweeper built by Weaver Brothers Shipyards, Orange, Texas: laid down 22 July 1941, launched 1942 (see date conflict), completed 15 August 1942, transferred to France as Marjolaine (D 337) on 30 September 1944, sold to France 21 March 1949, and struck from the US Navy Register 28 April 1949. NavSource explicitly notes no DANFS history exists for this unnamed hull.

- Limitations
- NavSource is the standard authoritative compilation for unnamed small craft; it is a secondary compilation, not a primary document. Its launch date (5 May 1942) conflicts with uboat.net and Navypedia (5 March 1942); Weaver sister-boat launch progression (YMS-68 launched 24 Feb 1942, YMS-71 launched 26 Mar 1942) favors March - conflict carried in gaps. 'Fate unknown' is NavSource's own cutoff at 1949, superseded by later sources for the Madagascar transfer.

- Finding
- Three independent authoritative compilations agree on the post-USN chain: YMS-69 was transferred to the French Navy on 30 September 1944, receiving pennant D 337 and the name Marjolaine (assigned 1947), and was transferred to Madagascar in February 1961 as Tanamasoandro.

French-period operational detail (Indochina station 1948-1950) appears only in forum-level sources and is excluded. Navypedia assigns pennant M656 to both D337/Marjolaine and D312/Tiare (ex-YMS-63) - an unresolved internal collision carried in gaps.

[7]Era inference built on: NavSource specification block (YMS-1 class, wooden hull, two General Motors 8-268A diesel engines, two shafts, complement 32) and the documented WWII design choice of wooden construction to resist magnetic mines (Texas Historical Commission marker text for Weaver Shipbuilding) [other_primary]

- Finding type
- asbestos_application
- Finding
- As built, YMS-69 was a wooden-hulled diesel-electric-free motor minesweeper with no boilers or steam plant; era-standard asbestos applications aboard a vessel of this type would have been confined to engine and exhaust lagging, machinery and flange gaskets, valve packing, electrical insulation, and limited fireproofing - materially less extensive than aboard steam-driven hulls.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming YMS-69 or Marjolaine was found in the public sources searched (see search_ledger). The hull's primary documentary trail (NARA deck logs and war diaries) contains operational records, not materials records.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard; a wooden diesel minesweeper carried materially less asbestos-relevant equipment than steam ships, and the hull has been out of US custody since 1944. CourtListener queries were attempted this session and blocked by the fleet pacing limiter - litigation status is open, not negative. Does not establish or defeat any claim of exposure or legal eligibility.

[10]Attribution collision check: postenavalemilitaire.com forum post identifies 'Marjolaine (D 337)' as 'ex-USS YMS-63'; Navypedia's own table separately lists 'D312 (ex-YMS63), 1947- Tiare, M656, 1951- P656' as a distinct hull [other_primary]

- Finding type
- historical_record
- Finding
- A French naval forum post misidentifies Marjolaine (D 337) as ex-YMS-63. The convergent record is that ex-YMS-63 became D312/Tiare while ex-YMS-69 became D337/Marjolaine: NavSource, Shipbuilding History, uboat.net, and Navypedia all identify D337 as ex-YMS-69.
