- Limitations
- NavSource is a curated naval history compilation, not the original Navy service card. The 1945 Navy book corroborates YT/YTB identity and builder, but precise dates, YTM reclassification, stations, and commercial fate await primary-document verification. The page says nothing about asbestos or exposure.
