What does a GRUNDVIG WOODWORKS INC HIN look like?

USCG records list GRUNDVIG WOODWORKS INC as out of business since 2009. That's common for older hulls — the HIN still decodes normally, and the out-of-business date helps date the boat and guides parts-hunting toward salvage and owner groups rather than a dealer network.
