Stavangerfjord & Bergenfjord 1924

My grandfather, Lars Slettedahl Sivertsen a naturalized American citizen, returned to Norway to visit relatives near Alesund in October, 1924 aboard the Stavangerfjord. I have a copy of the passenger list of the Bergenfjord showing he returned November 8, 1924 via Bergen to New York City. Does anyone have a source for the Stavangerfjord passenger lists? Recently I was given two black ribbons which look like armbands with the name Bergenfjord on one and Stavangerfjord on the other. Since I know he was aboard Bergenfjord on 11/8/24, the other must indicate his presence on the Stavangerfjord. Corrine Spector
