Three-antenna long-baseline interferometry at 10.7 GHz is reported for NRAO 150, 4C 39.25, 3C 345, VRO 42.22.01, and 3C 454.3 for several epochs between 1972 April and 1974 February. Simple models for the source brightness distributions fit the observations and indicate that most of the radio emission comes from one or two components. Component separations range up to approx.50 lt-yr, and component sizes are on the order of 10 lt-yr. Small variations in source structure have been observed.
