What does a GAJDOS FAMILY BOAT BUILDING HIN look like?

USCG records list GAJDOS FAMILY BOAT BUILDING as out of business since 2001. 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.
