- DANFS record for this hull ('Lamson II (Destroyer No. 328)'): laid down 13 August 1919 by Bethlehem Shipbuilding Corp., San Francisco, Calif.; launched 1 September 1920; sponsored by Miss Annette Rolph; commissioned 19 April 1921, Lt. Comdr. F. L. Johnston in command. After shakedown assigned to the Atlantic Fleet, arriving Charleston, S.C., 28 December 1921; operated along the east coast and in the Caribbean 1921-1925 (fleet maneuvers, war games, reserve training cruises). Assigned to U.S. Naval Forces in Europe, departed Boston 18 June 1925 for European and Mediterranean waters; returned one year later and rejoined the Scouting Fleet. Decommissioned at Philadelphia 1 May 1930; sold 17 January 1931 to Boston Iron & Metal Co., Baltimore, Md.; scrapped 18 October 1934. The entry's opening paragraph documents namesake Lt. Roswell Hawkes Lamson (USNA 1858, Civil War service aboard Mount Vernon and Gettysburg, powder boat Louisiana at Fort Fisher, died Portland, Oreg., 14 August 1903).

The stricken date (22 October 1930) does not appear in this DANFS entry and rests on secondary sources. 'Wansemont River' in the NHHC transcription is an apparent typo for the Nansemond River.

- NHHC Online Library of Selected Images page for this hull identifies Lamson as 'a 1190-ton Clemson class destroyer' built at San Francisco, commissioned April 1921, sent to the Atlantic late that year for East Coast/Caribbean operations, deployed to northern European waters and the Mediterranean June 1925 to mid-1926, and decommissioned in May 1930 'as the U.S. Navy swapped well-worn active destroyers for relatively fresh ones taken from reserve'; sold for scrapping January 1931. NHHC photo captions place this hull at Philadelphia Navy Yard 31 May 1923 (NH 43453), alongside USS Whitney (AD-4) in the Hudson River 2 May 1927 (NH 45093), and at Venice 3 April 1926 with Destroyer Division 27 (NH 86200: Preston DD-327, Lamson DD-328, Coghlan DD-326, Bruce DD-329).

Operational and building data: laid down by Bethlehem Steel, San Francisco, 13 August 1919; launched 1 September 1920; commissioned 19 April 1921; decommissioned 1 May 1930; stricken 22 October 1930; sold 17 January 1931 to Boston Iron & Metal, Baltimore, and broken up for scrap. A seven-officer commanding-officer list (Lt./LCDR F. L. Johnston through LCDR R. A. Lavender, ending 1 May 1930) is consistent with a single continuous commission.

- NavSource is a volunteer-edited secondary compilation, not a primary specification - its stricken date (22 October 1930), crew figure (114), and machinery data are carried as the only located source but are unverified against a primary document; the DANFS entry confirms the build/disposal dates but carries no spec block or strike date. Displacement (1,215 t) conflicts with the NHHC page's 1,190 t - logged in gaps.

- Metadata correction (per batch brief): the production source labeled this hull's class 'Hopkins'; no Hopkins class exists in the U.S. Navy destroyer program (USS Hopkins DD-249 was itself a Clemson-class destroyer). NHHC identifies DD-328 as 'Clemson class'; construction data (Bethlehem Shipbuilding Corp., San Francisco, laid down 13 August 1919, commissioned 19 April 1921) fall inside the Clemson-class build program (DD-186 through DD-347, built 1917-1922).

No DD-328 drawing, material schedule, or insulation section was retrieved or reviewed; holdings are not evidence of asbestos aboard. The 1945-1955 microfilm series window postdates the hull's 1934 scrapping (the file unit presumably films earlier drawings).

- Finding
- Era anchor: a peer-reviewed history of asbestos in shipbuilding states that 'in 1922 the US Navy specified asbestos use in new submarines,' with South African chrysotile specified for gaskets, insulation, packing, and tape. This places an official Navy asbestos material specification within one year of this hull's April 1921 commissioning - i.e., the service's asbestos-specification practice overlaps this hull's construction/outfitting era.

- Finding
- Era disposal context: NHHC's official chronology records the London Naval Treaty signed 22 April 1930, 'which carried forward the general limitations of the earlier [Washington] agreement and provided for further reductions of naval armaments.' This hull was decommissioned 1 May 1930, stricken 22 October 1930 (secondary-source date), and sold 17 January 1931 - a disposal timeline coincident with treaty implementation, when scores of flush-deck destroyers left the list.

- Zero counts apply only to the two opinion queries that completed; the docket index was not searched (pacing). A zero count does not prove no complaint exists - complaints not indexed, settled cases, and state-court actions are outside the index. Three ships bore this name (DD-18, DD-328, DD-367); unqualified 'USS Lamson' allegations in asbestos complaints would most plausibly concern the WWII-era DD-367 (1936-1946), and any such hit is a name collision for this hull, not qualifying litigation.
