Paul: they are the first spring in set # 677526 and 677528.
They are for spring sets using 8 and 9 total leaves. They are the A type and fit both half and three quarter ton trucks of the 2R series. May even fit the M series I did not check. Though Studebaker did use the turned down eye on later springs these will work just as well on the 3R through E series truck giving a slightly higher front.
