We present high resolution HI and optical observations of three Barred Magellanic Spiral galaxies (SBm): NGC 3264, NGC 4288 and NGC 4861. These galaxies range from amorphous to prominently barred in morphology, and NGC 4288 and NGC 4861 are interacting with small gas-rich clouds. We discuss the impact of these minor mergers on the optical and HI asymmetry. We also derive dynamical masses and fits to the halo density profiles. Our results suggest that there is a wide range of disk/halo mass ratios amongst these late-type galaxies.
