Weeks during 1943 port calls, and a USCG Headquarters memorandum dated 1945-03-18 (NARA declassification project NW 63684) naming John W. Weeks as an EC2-S-C1 class vessel while documenting corrective lifeboat/life-raft measures for the EC2-S-C1 type ('elimination of the lifeboats, port and starboard, between #2 and #3 hatches and the installation of larger lifeboats on the boat deck, together with the installation of an improved life raft'). Documents wartime operation under the WSA/Army chain and a class-level equipment alteration during her service period.

    shipscribe is a specialist compilation by a recognized naval-reference author working from primary records (Ships' Data, MARAD files, NHHC files) - it is a secondary source, not the underlying record; its detailed dates are corroborated where checkable (title transfer 1951-03-19 and Yokohama bareboat 1946-05-20 match the MARAD status card exactly; stricken 1959-06-01 matches NavSource). Photo caption 'MCE 51' is a typo for hull 617 (MARAD card + NavSource + shipscribe ship notes all give 617). No asbestos or materials content.

    NavSource is a volunteer-compiled archive (not an official publication) used for spec/award/OIC data and veteran-contributed photo captions; overlapping facts verified against DANFS/shipscribe/MARAD. Its chronology is internally contradictory ('Placed out of service in 1952' then 'out of service, date unknown') and its 'scrapped in 1959' conflicts with the dated 1960-03-29 NHHC sale brochure - discrepancies logged in gaps. Armament 'none' conflicts with the visible 20mm mount in the 1952-54 photo. No asbestos content.

    Finding type
    asbestos_application
    Finding
    The U.S. Maritime Commission instruction manual for the EC2-S-C1 plant - the documented design of this exact hull - describes cylinder insulation of magnesia under sheet-iron lagging; insulation products of this era were commonly manufactured with asbestos fiber, and period steam-system gaskets, packing, and insulation felts commonly contained asbestos. Liberty ships were built to emergency USMC specifications during the period when the federal government had reserved asbestos supply for shipbuilding. Typical applications for the type: boiler and steam-drum insulation; steam-line lagging between boiler room and engine room; valve and flange gaskets; machinery packing; insulation in accommodation spaces and around the galley; brake linings on winches and windlass.

    Limitations
    Class/design documentation, not a hull record - the manual names the type, not this vessel, and does not itself state 'asbestos' content (magnesia lagging of the era was typically asbestos-fiber-reinforced, but the manual text is silent on fiber). Because this hull is a documented EC2-S-C1 the inference is design-level, not merely era-level, but asbestos presence aboard this hull remains not ship-proven. Does not establish quantity, location, condition, individual exposure, or causation.

    Second Circuit ruling addressing mesothelioma claims by a mariner aboard War Shipping Administration vessels; the court considered jurisdiction over a personal-injury claim against the United States for asbestos exposure aboard the WWII government merchant fleet - the same operating agency (WSA) under whose custody this hull served 1943-1951 before Navy title. Claims against the government were barred on discretionary-function grounds - the characteristic litigation posture for exposure aboard WSA-era hulls like this one.
