We discuss three intense galactic X-ray binary stars with low- mass companions: V1727 Cyg (X2129+470), CAL 87, and NP Ser (GX17+2). All three optical counterparts, despite literally decades of intensive study, exhibit important anomalies, not readily interpreted by conventional models. All three sources also lie in severely crowded fields, and in all cases the anomalies would be resolved if much of the light observed from the ground in fact came from a nearby, thus-far-unresolved superposed (unrelated) companion. Recent work on a fourth famous source, Circinus X-1, shows that this possibility is far from speculative: 15 years after the ``identification" of that object, the optical image has been resolved into three objects within 1.5'', revealing the true counterpart 1.4'' distant from the canonical identification. We propose here a very simple program of PC imaging to explore this problem. One of the three sources is already known to have at least one polluting companion 0.9'' distant, so precision multicolor magnitudes in that system are guaranteed to be of importance in unraveling ground-based photometry.
