- Authoritative Navy narrative of service milestones only - contains no asbestos, material, or exposure information. Does not establish conditions aboard or any exposure. 'In service' 1941 vs 'full commission' 1943 is a status distinction the sources make explicitly; a NARA photo caption elsewhere calls 25 July 1941 'the day of her commissioning' - conflation noted, not carried.

- Specialist reference compilation consistent with DANFS chronology - contains no asbestos information. Propulsion spec establishes a diesel-electric (no steam) plant. The page's own photo caption calls 25 July 1941 'the day of her commissioning'; the chronology correctly separates 'placed in service' from 'commissioned 2 January 1943' - caption conflation noted, not carried.

- Finding type
- historical_record
- Finding
- NARA's comprehensive logbook inventory lists two deck-log holdings for AN-8 (Boxwood): 7/25/1941-9/30/1941 and 3/6/1942-5/31/1942 - the in-service period in Puget Sound (Seattle duty, Rich Pass net line). These WWII-era logs are held at NARA College Park (RG 24, Bureau of Naval Personnel logs 1941+); they are not digitized. Log coverage dates are inventory dates, not commissioning/decommissioning assertions.

- Limitations

Contents not reviewed; no asbestos or exposure content is documented or implied. Digitization status may have changed - verify against the current NARA catalog.

- Finding type
- environmental_record
- Finding
- Washington Ecology site documentation for Yarrow Bay/Carillon Point confirms the former Lake Washington Shipyard property in Houghton (Kirkland): the yard converted from wooden to steel shipbuilding in the 1920s, expanded greatly 1939-1942, built 29 ships for the Navy and repaired nearly 500 vessels during the war. Ecology's assessment notes likely near-shore sediment impacts from yard operations - potential contaminants listed are tributyltin, heavy metals, PAHs, and semi-volatile organic compounds. Asbestos is not among the contaminants identified in this document.

[6]Era inference built on: NavSource machinery specification (Enterprise DSG-6 diesel-electric, no steam plant); NHHC DANFS construction record (steel net tender, 1940-41); Navy-wide asbestos-era program documentation (GAO HRD-80-2) [other_primary]
- Locator
- NavSource specifications block (propulsion); DANFS construction paragraph; GAO HRD-80-2 program documentation
- Finding type
- asbestos_application
- Finding
- A Navy auxiliary of 1940-41 construction falls inside the documented era of asbestos shipboard use (thermal insulation, machinery and exhaust lagging, valve and flange gaskets, pump packing, electrical insulation, fire-resistant materials). Because this hull is diesel-electric with no boilers or steam plant, the steam-plant application set (boiler lagging, steam-line covering, turbine insulation) does not apply - the plausible applications are the smaller diesel/auxiliary insulation set.

- Finding type

- Finding
- GAO documented the Navy's asbestos-protection program: Navy ships built or overhauled through the era contained asbestos insulation, and the Navy's 1975/1979 policies governed insulation removal and worker protection - the program-level backdrop for a 1941-built hull that spent its entire career inside this era.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or museum/environmental document naming YN-3/AN-8 was found in the public sources searched; 'USS Boxwood' returns zero opinions on CourtListener (remaining base queries pending fleet pacing - see search_ledger). No law-firm listicle content naming this hull was found; mesowatch's Lake Washington Shipyard page is excluded as a banned source class (marketing page, no primary sourcing).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - 1941 construction is era-consistent with asbestos use. Does not establish that asbestos is or is not present; does not establish or defeat any exposure or legal-eligibility claim. Litigation status is open until the remaining CourtListener base queries complete.

- Specification and milestone conflicts across sources, resolved toward NHHC DANFS/NavSource: (a) NHHC DANFS spec block reads 'dp. 700; l. 151'8"; dr. 10'6"; s. 14 k.; cpl. 40; a. 1 3", 2 .50-cal. mg.' while the hazegray DANFS transcription reads 'dp. 560; l. 163'2"; dr. 11'8"; s. 12.5 k.; cpl. 44; a. 1 3"' - two DANFS editions disagree on nearly every figure; NavSource lists 700 t.(fl)/805 t.(lim), 162'2", 11'8" lim, 12.5 kts trial, 4 officers + 44 enlisted, 3"/50 + 2 .50-cal + y-gun. (b) Alaska departure: NHHC DANFS 'departed Seattle 26 June 1943' vs hazegray 'sailing for Alaska 1 July 1943'. (c) Final disposition: DANFS and NavSource 'carried on NDRF vessel inventory through end of 1974, subsequent fate unknown' vs shipbuildinghistory.com 'Scrapped 1974'. (d) uboat.net treats 25 July 1941 as the commissioning date - conflates 'placed in service' with 'commissioned'. (e) Wikipedia infobox asserts 'Home port: Tiburon, California' - unsupported by DANFS text; likely conflation with Naval Net Depot Tiburon.
