    NavSource is a volunteer secondary compilation, not a primary registry - milestone dates were cross-checked against Shipscribe's Navy/contract-record compilation (which supplies the keel, strike, and return dates NavSource lists as unknown) and the Levingston yard list on shipbuildinghistory.com. Contains no asbestos content; 'never saw active service' means the asbestos record, if any, would attach to construction, RN service, or merchant life.

    Limitations
    Secondary compilation by a specialist researcher quoting Navy/MC record values - not itself the primary document; the per-ship note itself flags the MC sale record card as missing, so the Moran delivery rests on Navy records rather than a surviving sale card. Supplying dates NavSource leaves blank (keel 3 Jan 43; return 13 May 46; strike 13 Nov 46) is a documented improvement, not an assumption. No asbestos content.

R. 47.5; No. 07-60616, filed 2009-03-06; BRB No. 06-0821). Paul Pelaez 'worked for Levingston as a ship fitter in the 1960s and early 1970s, where he was exposed to asbestos'; he died in 2002 and his widow claimed LHWCA death benefits. An ALJ found a prima facie showing of compensability on the record without formal hearing; the Benefits Review Board affirmed in an unpublished opinion; the Fifth Circuit denied the petition for review - the issues before it were last-responsible-employer designation, penalties/fees, and jurisdiction, the parties having agreed the prima facie case was established.

    Yard-level evidence, not hull evidence: the documented exposure dates to the 1960s-early 1970s, two decades after this hull's 1943 construction, and the opinion names the yard, not this vessel. It corroborates asbestos presence/exposure at the builder yard in the asbestos era. Litigation-stage note: the exposure finding was made at ALJ level (prima facie showing, no formal hearing), affirmed by the BRB in an unpublished opinion, and the Fifth Circuit decided only insurer-liability/jurisdiction questions - reported at the ALJ-affirmed stage, not upgraded; opinion is unpublished and non-precedential (5th Cir.

    Finding
    CORRECTIONS - three identity errors circulate for this hull: (a) Argentine Navy tug YAMANA is recorded in some sources as 'ex ATA-126'; Shipscribe's class notes state the designation AT-126 was long out of use by the time Argentina acquired YAMANA in 1948, that YAMANA was one of the 18 Army 143-ft sisters built at Levingston, and that this hull (as ATR-48) is 'well documented as having become' the Moran tug - the ATA-126 attribution to YAMANA is wrong. (b) A separate hull carried ATR-126: Gulfport Boiler & Welding hull 244, delivered as ATR-126 and reclassified ATA-199 (later USS Undaunted) - searches for 'ATR-126' or 'ATA-126' in secondary material can surface that different ship. (c) tugboatinformation.com entries give Levingston 'hull #285' for this vessel; the Levingston yard list assigns ATR-48 to hull 284 (hull 285 was ATR-49/Vagrant) - hull 284 adopted.
