- Finding type
- historical_record
- Finding
- NARA's guide to asbestos research for Navy vessels through 1961 directs researchers to RG 19 ship engineering drawings, particularly S39 insulation and lagging and S48 piping; it cautions that deck logs and muster rolls are not direct evidence of asbestos materials.

- Limitations
- Research guidance for the era, not a Swatane drawing or specification. No S39 or S48 drawing for this hull was obtained, and the guide establishes no asbestos aboard her.

- Limitations
- The 1979 letters postdate Swatane's 1962 retirement and 1964 striking, discuss other ships and classes, and contain no Swatane entry. Their YTB figure is thermal-insulation weight, not asbestos weight, and must not be attributed to this tug. They do not prove Swatane's materials or exposure.
