- Finding
- NHHC's transcription of Trever's Pearl Harbor action report identifies the vessel as DMS-16 and places Mine Division Four at buoys D-7 and D-7-S on 7 December 1941, with Trever, Wasmuth, Zane, and Perry in the nested group.

- Zane specifications block (class Clemson) and 25 October 1942 narrative (Trever as sistership); Trever entry (Hopkins DMS-13 named separately)
- Finding type
- vessel_history
- Finding
- NHHC DANFS identifies Zane (DD-337) as Clemson class and expressly calls Trever its sistership. Trever is therefore corrected to Clemson class; Hopkins is a different vessel (DMS-13) named alongside Trever in Trever's DANFS entry.

- Limitations
- Class identity is supported by NHHC's class specification and sistership wording; this does not transfer Zane's complement, equipment, or asbestos condition to Trever.

- Locator
- Asbestos hazards section, general shipboard uses
- Finding type
- asbestos_application
- Finding
- The Navy's afloat occupational-safety manual says asbestos has been used aboard ships in insulation and lagging for high-temperature machinery, boilers, and piping, and in gaskets, wiring, some deck tiles and paneling, and packing. This provides fleet-level material context for investigating Trever's era, without identifying any product aboard Trever.

- Limitations
- Fleet-wide safety guidance is later than Trever's service and is neither a Clemson-class specification nor a Trever survey. No listed material is attributed to this hull; presence, quantity, and exposure remain unknown.

- Finding type
- historical_record
- Finding
- NARA's ship-asbestos research guide directs researchers to RG 19 hull-specific correspondence, General Information Books, specifications, and ship engineering drawings, especially S39 insulation and lagging and S48 piping, to establish whether a particular hull carried asbestos. Trever's DD-339 files and its 1942 and 1945 yard-period records are the next archival targets.
