Briggen Besta, 1850

Gulbrand Gulbrandsen Vinger told a reporter that he had emigrated in 1850 on "Briggen Besta" with Captain Skroder from Christiana to America. This Brig does not appear to be in the 1850 ship list on this site. None of the names listed seem to sound like "Besta". Obviously in the 72 years between emigration and the interview with the Norwegian speaking reporter for Skandinavn, he could have forgotten part of the name. The port probably would have been Kristiana or Drammen as he was from Hadeland. Gulbrand said there were about 100 passengers and the voyage required 10 weeks. He also said they landed in New York. Does anyone have any ideas or suggestions?
